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

[Perry, Aaron @ LSC]

Good Evening Jeff,

Thanks for taking the time to reply to my question!

I ended up putting the .gsf function script into my GASCRP directory and called it in my main script with: newday = convertday(fday).

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.

Good Evening All,

I'm currently trying to create a very simple function script (.gsf) where a weekday is changed from say "Sun" to "Sunday" and then plotted. I have sought help from a few people who are GrADS-proficient and they are as stumped as I am.

Here's what I'm dealing with:

Function Script:

function convertday(fday)

rc = gsfallow("on")

if (fday="Sun"); newday="Sunday"; endif
if (fday="Mon"); newday="Monday"; endif
if (fday="Tue"); newday="Tuesday"; endif
if (fday="Wed"); newday="Wednesday"; endif
if (fday="Thu"); newday="Thursday"; endif
if (fday="Fri"); newday="Friday"; endif
if (fday="Sat"); newday="Saturday"; endif

return(newday)

Command to function in main script:

'/home/aaron/grads/day_abv.gsf 'fday''

How I'm attempting to plot the variable:

'draw string 2.60 8.05 Valid: 'thour' 'tz' ('thour2') 'newday' 'fday2' 'fmonth' 'fyear''

Also, I'm using 'q time' fday = subwrd(result,6) to get the actual weekday name at the top of the main script.

This function should be working, as it's probably as simple as you could get for a function.

Any ideas?
