Language Overview


Functions

The core of the Zeus language is its ability to use functions. A function is a self-contained area in the program. It has itsown variable space and when no longer needed it will free up this space.

Functions can have any number of parameters passed to them. You can pass integer, floating point and string values to a

function as a parameter.

To pass a floating point value you must declare the argument as a single parameter.

In example 1.1 the data1 parameter will expect a floating point value to be passed. If the value passed is not a floatingpoint value it will be converted.

The next 2 parameters, data2 and data3, will expect integer values passed to them. Again, if the value passed is not aninteger values it will be converted. Notice that data3 does not have a declaration type. When the declaration type isomitted an integer value is assumed.

In addition to local variables all functions have access to global variables. This allows you to easily manage severalhundred variables in very little space.

Functions are totally self-contained with their own labels, gotos, gosubs and local constants.

In example 1.2 the function mymult will take a number and multiply it by its self and return the result.

Example 1.1

'example 1.1

func collect(data1 as single,data2 as integer, data3)

endfunc

Example 1.2

'example 1.2

func main()

dim x as integer

for x = 1 to 10

print x,"*",x,"=",mymult(x)next

endfunc

func mymult(tt as integer) as integer

exit(tt * tt)

endfunc

Setting a Functions Return Type

By default, when a function returns a value it returns a 32-bit integer. To return a floating point value you need to definethe function as a single value as shown in example 1.3.

Note: If a function is set to return a float and it is used in an integer expression the floating point value will be convertedinteger. This will allow you to write generic libraries.

Passing String Data

When passing string or text data to a function you need to define the parameter as string as shown in example 1.4

ImportantThe use of parentheses are NOT optional when using functions. Even when calling them with out returning values requthe use of parentheses.

Example 1.3

'example 1.3

func getpie() as single

exit(3.17)

endfunc

Example 1.4

'example 1.4

func main()

disptext("hello")

endfunc

func disptext(tstr as string)

print tstr

goto again

endfunc

Language Overview


Variables

There are three types of variables in the Zeus language: 32-bit signed integer variables, 32-bit signed floating pointvariables, and string variables. All variables may be assigned as local or global variables.

Local VariablesWhen a variable is local, the space it takes will be freed up once the function in which it was declared has exited. This notonly saves memory but also helps you encapsulate your functions.

In example 2.1 the three variable slots taken up by the x,y,z variables in function displaystuff will be freed up for use byother functions once the displaystuff function has exited.

To declare a local variable use the dim statement.

To create an integer variable use:dim x as integerordim x

To create a floating point variable use:dim x as single

To create a string variable use:

dim x as string

Global VariablesWhen a variable has been defined as a global variable it can be accessed by all functions. Global variables never goaway.

To declare a global variable use the statement global. Global variables may be declared anywhere, even outside functions.

To create a global integer variable use:

Example 2.1

'example 2.1

func main()

dim myvarb1 as integer

displaystuff()endfunc

func displaystuff()

dim x as integer

dim y as integer

dim z as integer

print x,y,z

endfunc

global x as integerorglobal x

To create a global floating point variable use:global x as single

To create a global stringt variable use:

global x as string

Variable ScopeIt is possible to have a global variable called zzz and a local variable called zzz. In this case the local variable will takeprecedence while in the function that created the local variable. The same is true for constants.

Variable/Constant/Function/Label names

Name lengthThere is no limit to the size of the names.

Valid CharactersThe first digit in a name must be a letter or underscore. After the first digit is defined you may use numbers in the name

How manyThe amount of available RAM determines the actual number of variables that can be active. That is to say you can havseveral local variables defined but if the function is not currently being called the variable does not take any space.

You may have up to 1,000,000 string variables, 1,000,000 integer variables, and 1,000,000 floating point variables. Thelimits only apply to local variables so each function may have this many variables.

Constants

Constants are numbers that are referenced by a useable name. For example, const CLK 5 would allow us to use the wCLK to represent the number 5. That way you can have several references to the CLK port. To change the port from 5 means only having to change 1 line of code as shown in example 2.2.

Once a constant has been defined the value cannot be changed. In other words you can't have the statement CLK = 25

Constant statements are local to the functions that they were declared, just like local variables.

Example 2.2

'example 2.2

func main()

const CLK 5

print CLKprint int(CLK *5)

endfunc

Language Overview


Global Constants

You can also define global constants, i.e constants that are available to all functions. To define a global constant use thegconst statement just like you would use the const as shown above.

Global constants can be defined anywhere in the program file.

Note: Constants may hold both floating point and integer values. They cannot hold string values.

MATH

The Zeus language supports two types of math: 32-bit integer math and 32-bit floating point math. In many cases the twoare interchangeable but there are some subtle differences.

Integer Math

The following operations are supported:

* Multiplication\ Division Truncate Result with remainder/ Division Rounded result with remainder+ Addition- Subtraction& And| Or^ Xor// Return the Remainder after a Division

You can use math anywhere an expression is used or in variable assignments.

Example:

dim res as integerres = 10 + 5

Floating Point MathFloating point math is very similar to integer math.

The following operations are supported

* Multiplication\ Division result is truncated to integer. Decimal is chopped off./ Normal floating point division+ Addition- Subtraction& And| Or^ Xor// Return the Remainder after a Division

You can use math anywhere an expression is expected.

String Math

There are a couple operators that are supported when working with strings.

+ Add strings- Subtract the contents of the string on the right side if it exists on the left side.

Math and Expression Conversion

By its nature Zeus will automatically convert one data type to another. This is fairly strait forward when working withintegers and floating point numbers. However Zeus will also attempt to convert to and from strings as well.

dim tstr as stringdim x as integer

x = 25tstr = xprint tstr

In the above example the integer variable will be converted to the string as 25 so will print 25.

dim tstr as stringdim x as integerdim y as integer

x = 25

y = 75tstr = x+yprint tstr

In this example the x value will be placed in the string as 25 and the y value will be added to the string as 75 with thresult being 2575. This is because string math is being used. If you actually wanted to add x and y you need to force compiler to use integer math when adding x and y as shown here.

x = 25y = 75tstr = int(x+y)print tstr

What affects the type of expression math to be used? When doing assignment to a variable the variable type willdetermine the type of expression math used. If using an expression in a function or command parameter then theexpected type will determine the math used.

Language Overview


Conversion Options

You can set how the Zeus language handles conversions by setting various conversion options.

option cvtstringtoint xxxoption cvtstringtosingle xxxoption cvtsingletoint xxxoption cvtsingletostring xxxoption cvtinttosingle xxxoption cvtinttostring xxx

Where xxx is the type of conversion to allow.

autoWill cause an automatic conversion from one type variable to another. You can alwaysoverride this with the cint/csng/cstr/val commands

warnWill do the same as auto but will cause warnings to be generated.

errorWill stop the compiler with an error

There are also three global settings

option cvtautoplaces the compiler in automode (The default mode)

option cvtwarnCauses a warning.

option cvterror

Causes an error

Constant Conversion

The compiler supports three types of number or constant conversion.

Binary ConversionYou can assign a binary number to a variable or as part of an expression by preceding the number with a %.

Example:res = %100

res will contain 4. Note that the MSB is on the left side.

Hex ConversionYou can assign a hexadecimal number to a variable or as part of an expression by preceding the number with a $.

Example:res = $41


13/177

Language Overvie


res will contain 65.

ASCII conversionYou can convert an ASCII character to a byte by enclosing the character in single quotes.

Example:res = 'A'

res will contain 65

Error Handling

There are 4 modes for handling runtime errors. These are errors that are not handled by the compiler.

onerror goto labelWill case the engine to jump to the label after the error has completed. The label must be located in the function whereerror is expected.

onerror console (default)Will display an error message in the console window.

onerror resumeNo action is take the program just keeps running ignoring the error.

onerror noneNo action is taken at the command level. The current function will exit and a message will be displayed.

While every attempt has been made to catch all runtime errors. There are always a few that may slip through the crackyou encounter any unhandled errors please make a note of the circumstances that caused the error and drop us a line www.kronosrobotics.com.

The same goes for conversion warnings. If you notice any that don't seem to fit the settings you have placed in your cosend us a short example showing the anomaly.

Arrays

You can create floating point, integer and string arrays. An array is a block of the same kind of variable that can beaccessed with an index. This effectively allows you to cycle through a list of variables. Both single dimension Z(x) anddouble dimension arrays are supported Z(x,y)

Integer Arrays

Creating an integer array works just line creating normal integers. You simply need to add a bit more information so wecan tell the compiler how many we want to define.

dim myvarb(10) as integer

Will create a block of 10 32-bit integer variables. You can access each individual element by using the index. Note thatfirst array element is 0 so in this case we will use 0-9 to represent the elements.

myvarb(0) = 5000 'The first element in the arraymyvarb(9) = 400 'The last element in the array

14/177

Language Overview


Floating Point Arrays

Float arrays work just like integer arrays. The only difference is that we will use the float declaration instead of integer.

dim myvarb(10) as float

This will create a block of 10 floating point variables. Again you can access each element by using an index.

myvarb(0)= 2.76 '1st elementmyvarb(2)=300.54 '3 rd element

String Arrays

As with integer and floating point arrays you may create string arrays.

dim mystring(10) as string

This will create 10 strings that you can access via an index number.

Array exceptions and rules

You can use arrays in any expression. Automatic conversion will take place between each type.

You can not pass the whole array to a function. Only a single element can be passed. You can use global variable arraysto manipulate array data in different functions

You can not return whole arrays with the exit command. You can only return a single element.

When a command requires a variable for data return you my not use an array.

You can not access individual bits and bytes of array elements. For example myvarb(1).bit(7) is not currently allowed..

There is no bounds checking on arrays so if you index outside the allocated block you will access data in other variables.

_ Continuation Operator

This character can be placed at the end of a line. This tells the compiler that the current line continues to the next line.This is useful when doing tables as well as lookup and lookdown commands. The continuation operator can not becontained in quotes.


15/177

Command Synt


In the following section the actual syntax of each command will be shown. Each command name will be followed by asyntax example and a syntax parameter type. Commands may be upper, lower or mixed case.

Some commands can be used as standalone or in expressions. When used in expression the command may take on different action and it will be noted in the explanation.

The paramater types will be indicated as follows:

exp:Any variable type, literal mathematical expression. The parameter is expected to be numberic as a floating poior integer. If a string is passed it will be converted to a numberic before being added to the expression. A Iexp orFmay also be used to indicate that the type of numeric data prefered.

Sexp: This is a string expression. The parameter is expected to be a string . If numeric data is passed it will beconverted to a string before being addded to the expresion. So 5+5 in a string expression will be 55 not 10.

varb: Variable accepted only. No arrays, bit or byte extensions. The command may also specify the type of variableusing Fvarb, Ivarb or Svarb.

label: Valid location label.

number: Can contain only a number or constant.

operator: Valid operator as in > < >=

If you use the Select Case itdefaults to a Selection type of string that will work with all values. If you areusing Integers then a Select Integer will run much faster than the other types.You need to also keep this in mind if you are going to use math in theexpression.

Value - This is a expression that will represent the value that we will try tomatch up with a Case command. Again note that the default type of stringuses string math when calculating this expression. It may be necessary touse a Int() or Float() function to encapsulate your math. You can alwaysuse the raw Select Integer or Select Float for better and faster numbercomparisons.
