What do you mean by arrays

Data, parameters. Please specify in more detail exactly what it is you want to know.

Do you mean stem variables ?

Hello anilsanda and welcome to the forums,

Please keep in mind that while your question is quite clear to you, it may not be to others.

If you can give an example of what you have and what you want to do, that will help.

Anilsanda,

I have not yet discovered a way to pass "arrays" from one Rexx program to another. I don't believe there is a way to do it using Rexx exclusively but --- I hope that somebody can tell me I'm wrong on that.

As expat pointed out, in Rexx an array is actually a stem variable. Let's say your program uses the following variables:

id.0
id.1
id.2
id.3
counter
name

In our mind, we think of the id variables as belonging to an array. But in many ways REXX treats each id variable as being separate and unrelated variables.

Sometimes I will pack repeating data into a single REXX variable and pass the variable. Dirty but it works...

If you are wanting to pass data between Rexx programs, I would
use the QUEUE command, you also would want to look at NEWSTACK
and DELSTACK, the PULL commands. You can not pass a STEM array
between Rexx programs. There are 2 assembler programs on the CBT
website call STEMPULL and STEMPUSH that will allow for this function.
