There is an OOP concept called an accessor or getter. I am not finding a succinct definition on the Web but perhaps you can.
Anyway, as an alternative to generating the four fields you describe below, you might consider generating accessor routines. (This is on the output side of things and independent of AREAD, ADATA or SYSPRINT input.) Assume the following is the record to be accessed from Rexx: CLIENT DSECT LASTNAME DS CL16 FRSTNAME DS CL12 ZIPCODE DS F BIRTHYR DS H The program would return the following Rexx code (untested): LASTNAME_Get: Return SubStr(Arg(1), 1, 16) FRSTNAME_Get: Return SubStr(Arg(1), 17, 12) ZIPCODE_Get: Return C2D(SubStr(Arg(1), 29, 4)) BIRTHYR_Get: Return C2D(SubStr(Arg(1), 33, 2)) Now your Rexx application programmer could code lines like the following (assuming CLIENT_Rec contained a CLIENT record): Say "Client" LASTNAME_Get(CLIENT_Rec) "was born in" BIRTHYR_Get(CLIENT_Rec) Charles -----Original Message----- From: IBM Mainframe Assembler List [mailto:ASSEMBLER-LIST@LISTSERV.UGA.EDU] On Behalf Of Joseph Reichman Sent: Sunday, January 2, 2022 7:07 AM To: ASSEMBLER-LIST@LISTSERV.UGA.EDU Subject: Re: Determining a group item My initial thoughts were having the copybook preceded my AREAD Bottom line with AREAD I get the entire 80 byte assembler sysin Many have said I can’t do this way I may give it a try I need to generate 4 fields for rexx 1) address of the name 2) length of the name 3) address of the value 4) length of the value > On Jan 2, 2022, at 8:16 AM, Paul Gilmartin > <00000014e0e4a59b-dmarc-requ...@listserv.uga.edu> wrote: > > On Jan 2, 2022, at 01:15:38, Martin Trübner wrote: >> ... >> For the record: My HLASM debugger eats source code to support >> source-debugging. >> > Does it grok SYSIN and SYSLIB in z/FS files? > > -- gil
