Idle speculation: it's the file name of s bit map meant to go into the manual and the text was supposed to say SYSPROC.

What might this be a relic of? GRX does not seem to be a component prefix. I could be wrong. Here's my theory: a developer whose initials were GR added some sort of debug output: GRXBIMG = George Rothwell's Extended Byte Image or something like that. It somehow made it into the product documentation. Astounding that it has hidden there in plain sight for over twenty years. I do not see the reference in the 1991 MVS/REXX Reference: http://secure-web.cisco.com/1msRUVNTCVPM6al9HyShyRDCsU6ONoAtBXbZbF7GJI59Gj89EEVWxcw_sygtcmoro-Imjk1U0ivgPs56TezTZL7Ba2WK1xNb6Yt-8QhSSHtfKcjpi4120Lk2HeTC2GP_IBVSjpDZ2aER63S8t_e86YAeMWGEkxm-0kO-Skka5_F7n-9WQmSxHedXSSqNjPMCsTlIWQCC56yaSIKzebhds42QUBcHC9zlx-UMb5yTFa2oIWvz0WrXbUGm2BF2bLLjlEhdCanddWLM-oXiVALYstYbU2hWeGN7BMRxMcJFPaMNmBxidchg_eoJCTNNqeCY_q74Di2uFtY4YQx2Y89PNJ8tAou1-jxWUZ1teZbByjfqzH8hUIH2VQUbpBvenpMTw1T4CneetfQe7qvCqp5o2OSE52nYpPrr4XGXLb1VNGnwTSrzLKz3fW4A6bNBpdw-r/http%3A%2F%2Fwww.bitsavers.org%2Fpdf%2Fibm%2F370%2FTSO_Extensions%2FSC28-1883-4_TSO_Extensions_Version_2_Procedures_Langage_MVS_REXX_Reference_Aug1991.pdf Charles -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Paul Gilmartin Sent: Wednesday, June 3, 2020 9:16 AM To: [email protected] Subject: Re: What is GRXBIMG On Wed, 3 Jun 2020 07:00:19 -0700, Charles Mills wrote: >I must have time on my hands.

I'm curious. Does: //GRXBIMG DD DUMMY suffice, or must it be a PDS(E)? What error is reported if the programmer fails to allocate GRXBIMG? Is this covered in M&C?
