Saw it mentioned it the TK5 manual (TK5-Introduction-and-User-Manual). Which also said…BREXX is a nearly fully compatible clone of IBM’s REXX. Samples here BREXX.V2R5M2.SAMPLES. Saw Primes. How do I execute it. I saw something like RX ‘BREXX.V2R5M2.SAMPLES(PRIMES)’. So I dropped down to TSO and I tried RX PRIMES. I took a chance that the “path” was somehow defined, and simply tried RX PRIMES. It returned “Bad arithmetic conversion”. Not a very friendly error. I assumed it was looking for a number of how many to generate. So I tried again…RX PRIMES 20. It worked!
Then I tried…RX PRIMES 32767. It kinda hung and the CPU was pegged. Finally it bombed…but hung the terminal. Luckly I could cancel the user /c u=herc01…and that worked. I logged back on and tried…
Maybe I should try and get my VM/370 REXX calendar program,working in MVS/TSO.
Note: When I dropped out of the main panel I was wondering how to get back. I tried TSOAPPLS but that didn’t work. I guessed ISPF, and…that worked!
As great as I think REXX is on MVS, I think it’s even more important on VM/370. Especially because DOS/VS doesn’t have a development environment like MVS/TSO already has.
