pro pro1, FileName_In, FileName
; Change it
FileName = FileName_In + "_changed"
end

pro pro2, FileName
; Retrieve the new value
print, FileName
end

IDL> pro1, 'Junk', FileName
IDL> pro2, FileName
Junk_changed

Is this what you wanted?

Use the COMMON statement. You can find the description in the online help.
Hope this helps,
