It works perfectly now. Excellent example you provided. I had previous
read the tutorial provided, but never really understood the implications of it
all until I saw your example. It makes perfect sense now.
Thanks so much for taking the time to help. Would have never
figured it out on my own. <o:p></o:p></span></p>

Subject: Re: [gradsusr] Pass Data via the 'Return' Expression<br>
<br>
Hi Mark,<br>
<br>
Please find attached main.gs (calling script) and add1.gsf (GrADS script <br>
function).<br>
<br>
***********************<br>
* Main script<br>
***********************<br>
<br>
rc = gsfallow("on")<br>
<br>
iVal = 1<br>
<br>
say 'iVal = 'iVal<br>
say 'Making Call to GrADS script function "add1"'<br>
<br>
oVal = add1(iVal)<br>
<br>
say 'Call Made - Checking for Answer'<br>
<br>
say 'oVal = 'oVal<br>
<br>
Try using GrADS main script as follows:<br>
<br>
ga-> main.gs<br>
iVal = 1<br>
Making Call to GrADS script function "add1"<br>
input val = 1<br>
new val = 2<br>
Passing Variable Back to Main Script<br>
Call Made - Checking for Answer<br>
oVal = 2<br>
<br>
<br>
in main.gs, a call is made to an external user-defined script function <br>
"add1.gsf" (<a href="http://grads.iges.org/grads/gadoc/gsf.html"
target="_blank">http://grads.iges.org/grads/gadoc/gsf.html</a>) and can
be <br>
called from *outside* of main.gs because of "rc =
gsfallow("on")" in <br>
main.gs and because of the suffix "gsf" for "add1.gsf"...<br>
<br>
first, if only the line "rc = gsfallow("on")" is commented
out (add1.gsf <br>
exists), the result (you can try this):<br>
ga-> main.gs<br>
iVal = 1<br>
Making Call to GrADS script function "add1"<br>
Function not found:
add1 <br>
Error occurred on line 12<br>
In file main.gs<br>
<br>
next, if the line "rc = gsfallow("on")" is active, but
add1.gsf is <br>
renamed to add1.gs (you can try this):<br>
ga-> main.gs<br>
iVal = 1<br>
Making Call to GrADS script function "add1"<br>
Function not found:
add1 <br>
Error occurred on line 12<br>
In file main.gs<br>
<br>
Hope this helps,<br>
