Use the TRACE instruction. There are a few different parameters, depending on what kind of trace you require. Check the REXX Reference Manual for the list of parameters. My personal favorite is TRACE I (to activate an Intermediate trace) followed by TRACE N (to disable the trace).

I would suggest the TRACE R option if you are not accessing a lot of values.

Ya TRACE is the best option to debug a REXX routine. But if your program is too long, you may lose your control over the program. Then I think you can use -
1. The postions where you are thinking a faulty position, insert a SAY statement.
2. If any wrong responses are coming then you can also insert "SAY rc zerrlm" - statement. This will tell you the return code of the previous statement executed and also the reason of the error (in words).
