[gradsusr] Custom (And Simple) Function Script Refuses To Pass Variable Back To Main Script

[Jeff Duda]

I'm not 100% sure how returning a variable works when the function code is
contained within a different script file, but when you call it, the syntax
should be something like

fday2 = 'run /home/aaron/grads/day_abv.gsf 'fday

if that doesn't work, put the function code within the script you're
actually running.

Also, you can try making newday a global script variable by renaming it
with a leading underscore.  Then you may be able to access it from your
other script code just by virtue of having run the day_abv function in your
script.
