Betreff: Re: [h390-vm] How is BRexx different from Rexx? ? Hello Bertram, ? the main differences are: - Different I/O methods (no EXECIO) *1
- the numeric precision is limited to 32-bit
- z/OS REXXAPI is not supported
- no ISPF support (z/OS) *2
- no TSO LMxxx support
- not compilable
- some minor differences in REXX functions (e.g. PARSE with templates)
? We have created and supported BREXX/370, which is an extended BREXX version for MVS3.8 and added some of the missing features: ? - *1 EXECIO? is contained
- *2 limited ISPF support
- Formatted screens as ISPF is not part of MVS3.8
- VSAM I/O (KSDS)
? I have no details for BREXX for VM. ? As I come originally from z/OS I can say the basic features of IBM REXXX and BREXX are very similar. The conversions to BREXX were in the above-mentioned areas. ? Regards ? Peter Jacob ? ? ? Hello, As suggested, I'll be writing the BM Backup program using Rexx / Brexx.? I would appreciate knowing the differences because the goal is for the project to run on both VM/CE & real iron.
