PURPOSE:This utility is used in a batch file to set an
environment variable
to a value or create a new environment variable.
An example would be if you had a replacement for the DOS "TYPE"
command suchas the "BROWSER" utility which did not prompt you for a
filename if youjust issued the command "BROWSER" but instead gave
you a nasty error message.This utility can get around this by
letting the batch file prompt you for afilename, as it does in the
example below.
USAGE:To use it, the batch file command is:
"envset TEMP.BAT ENAME"where:-TEMP.BAT is the name of a
temporary batch file which will containthe fully written command to
set the environment variable.-ENAME is the environment variable you
wish to use.
EXAMPLES:
Listing of file browse.bat:
@echo offif not "%1" == "" goto nameecho Please enter the
filename to be browsed,echo and press "Enter":c:\tools\envset
c:\temp01.bat tempnamecall c:\temp01.batc:\utils\browser
%tempname%set tempname=del c:\temp01.batgoto
end:namec:\utils\browser %1
:end
If a filename is entered at the command line after the command
"BROWSE",then the utility BROWSER in directory c:\TOOLS is
executed. If the command"BROWSE" is entered with no filename to be
browsed, then ENVSET is run toask for interactive input to get a
filename to be browsed.
The utility ENVSET will ask for a filename to be entered, then
set theenvironment variable "tempname" to that filename. It then
runs the"BROWSER" utility with that filename as input and then gets
rid of theextra TEMP.BAT file and the unnecessary environment
variable TEMPNAME
