Loop Control Variable Not Working

[djmordigal]

Hello all,
I'm new to this forum, so forgive me if this question has already been asked or if I'm not posting in the right place.

I'm a student on co-op, and new to the REXX language, so I'm experimenting with some different things. One of these things is arrays.

On my computer, I have a REXX interpreter that runs the following code just fine:

[tt]
SAY "Enter a value"; PULL value;
array.1 = value;
array.2 = value*2;
array.3 = value*3;
DO i=1 TO 3
SAY array.i;
END
[/tt]

And say, if the user puts in 2, outputs:
[tt]
2
4
6
[/tt]

as expected.

But when I load the same file onto the mainframe and run it under NetView, it's reaches the line that says [tt]SAY array.i[/tt] and complains [tt]"Invalid character in program."[/tt] I'm thinking it's an issue with different versions of the REXX interpreter on my computer vs. the mainframe I'm running it on?

Has anyone else encountered this issue or know of ways to get around it/other ways to treat an array in REXX?

When you transfered the source from PC to the Mainframe, it could be ASCII/EBCDIC conversion problem
or something with the PDS settings like here

Also note: Rexx does not have 'arrays'. They look like arrays but the correct terminology is 'stem variable' with a stem and a tail. I heve never tried running under netview - what happens when you run it from a tso session. Note that you need a comment with 'Rexx' somewhere in it as the first line when running on the mainframe.

Yes, I did remember to include the [tt]/* REXX */[/tt] comment. I also fixed the issue this morning. Turns out that it didn't like the tab character at the beginning of that line. I'm using a Windows-based text editor and transferring that file to the mainframe via FTP, so it got encoded differently.

I've since changed the settings in my text editor so that when I hit the TAB key it just inserts 4 individual spaces. Works fine now.
