There are equivalents to almost all of those listed above. As Timothy already mentioned ZAOU has many functions including calling MVS programs which covers all the ATTACH/LINK stuff. For BCPII there is a REST API which has more function then the REXX so you can just call that. Calling REST using the Python requests package is trivial and decoding JSON is one line of code. You can easily wrap a REST API into a Python library, see the Zowe SDK for Python that has classes for submitting jobs, processing output, console commands etc https://github.com/zowe/zowe-client-python-sdk. ZAOU also has classes for this. Obviously, bpxwunix isn’t required because you can just use the Python runtime to run a subprocess. For dsnrexx there is ibm_db Python package https://github.com/ibmdb/python-ibmdb. This is actually part of the IBM DB2 Connect but is open source and free to use. For FTP that’s covered by the Python standard library, although it may need work for MVS data sets. For irrxutil there is pyRACF from IBM https://github.com/ambitus/pyracf. Shameless plug: While ZAOU has classes for MVS data set I/O they’re lacking for VSAM and still need a lot of work for processing large data sets one record at a time. My pyzfile package handles all types of data sets, including VSAM which REXX does not https://github.com/daveyc/pyzfile. For chasing control blocks I have written another library with support for memory snooping https://github.com/daveyc/pyzutil/blob/master/examples/cpuid.py which is much cleaner then the usual intractable nested c2d(c2x(storage))) functions calls using REXX. > Is there a python/rexx mapping (official or otherwise) similar to JES2/JES3 > command mapping? > > ---------------------------------------------------------------------- > For IBM-MAIN subscribe / signoff / archive access instructions, > send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
