get return value from .gsf function

[Pablo Romero]

I've never been able to get the following to work: use the 'return(varname)' statement within a .gsf function to return a value.

I've only been able to accomplish the passing of variables around between scripts by using '_varname' global variables. This defeats the whole purpose of creating a script function.

I want to create a .gsf function that can actually return a value that can be directly assigned to a variable in a .gs file. example:

*gsf file, addit.gsf
function addit(var1,var2)
sum=var1+var2
return (sum)

*test gs file, tst.gs
rc = gsfallow("on")
tx=addit(2,3)
say '2+3 is 'tx


this doesnt work...it simply prints '2+3 is ', so the gsf function is NOT returning the value of the 'sum' variable...

Is this by design or am I doing something incorrectly?
are global variables the ONLY way to pass variables between script/script function files?
