Vista Tutorial - returning values to original script

Hi,

I have a script called menu.ps1 which calls another PS script,
getvalues.ps1. In getvalues.ps1, I do some console interaction with the
user. Depending on the interaction, I need to return a value back to the
original menu.ps1 script. I tried to do a return "$value" but that didn't
work. What did work was to define a global variable via: $global:testvar.
Is that the best way to return a value back to the original script? I rather
not use a global variable if I didn't to.

Thanks,

Basically anything output by a script that is not redirected to a file or captured by a variable is consider the output of a script. Try this:

24> 'gps | ?{$_.PM -gt 50MB}' > memhogs.ps1
25> $hogs = .\memhogs.ps1
26> $hogs

In fact the trickier problem is getting rid of unwanted script output i.e. some innocous like this:

"Starting script memhogs.ps1"

is added to the output of your script. To avoid that you would do this:

write-host "Starting script memhogs.ps1"
