Checking a list ...

[CameronY]

How do I check to see if the %Instance% entered by a user exists in space separated variable ....

[highlight]set BOS-Instances=demo live qa train[/highlight]

Not entirely sure how to write what I suspect will be a FOR routine to handle this.  If the %Instance% entered does not exist in the list, then I'll have it exit the script.

Thanks in advance.

You need to effort a little bit more.  
You can do it with the old FOR of MS-DOS

Code: [Select]

@echo off
set BOS-Instances=demo live qa train

set Instance=
set /P Instance="Option: "
for %%x in (%BOS-Instances%) do if /I "%Instance%" EQU "%%x" goto GOOD

:BAD
echo Bye
goto :eof

:GOOD
echo Value: %Instance%
