Not that I found. But I take it as a given they maintain an un-squished version. By the way, I did not come up with that technical term. They all have header comments like this:

Years ago while disabling some built-in automation in SA for z/OS I found that the REXX code SA actually ran live was almost all "squished." I didn't dig into it, but I assumed (I still believe safely) that it was to reduce interpreter overhead. I just took a look at it tonight to see how the efficiency-minded SA developers coded keywords. A brief look says the majority are first-letter capitalized (as Mike said to do, I believe--which is the reason I always have) or completely capitalized; however, there are enough exceptions to make me wonder. By the way, if you haven't seen it, here's a snippet as an example. It is really . . . something: If cond = 'NOVALUE' | cond = 'HALT' Then rc = 'N/A';Select When cond = 'HALT' Then desc = 'CLIST HALTED' When cond = 'SYNTAX' Then desc = errortext(rc);When cond = 'FAILURE' Then Do If rc = -1 Then;desc = 'COMMAND NOT FOUND';If rc = -3 Then desc = 'COMMAND NOT PERMITTED';End;Otherwise Nop;End "AOFMSG "cond",760,LOG,"loc.0me","sigl","rc",'"desc"'";Call Aof_Exit -5;Exit -5 Aof_Silent_Error:;Call Aof_Exit 0;Exit 0;Aof_Exit:;Procedure Expose loc. Do ix = 1 to Words(loc.0claim_tickets);ticket = WORD(loc.0claim_tickets,ix) Call INGPXDEL ticket;End;if loc.0UserExit = 'Y' then;call @User_Exit lrc = Arg(1);If Arg(2) <> 'TEXT' then;If datatype(lrc,'W') ^= 1 Then lrc = 0 Select;When cglobal('AOFDEBUG') = 'Y' Then "AOFMSG" loc.0me",702,LOG,"time()","opid()","lrc;When loc.0debug = 'Y' Then Call Aof_Debug 'COMPLETE, RC='||lrc||'.';Otherwise nop;End;Exit lrc First Horizon Bank Mainframe Technical Support -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Jeremy Nicoll Sent: Monday, November 23, 2020 9:50 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: Has anyone integrated Rexx with IKJPARS?

I thought that environment (after address) was one of the few places in REXX where quotes were unnecessary because what's typed there is regarded as a constant.

Even if what you said above was true, I doubt very much that capitalising the environment name would ever have make a measurable difference, bearing in mind how few times one would typically specify an address statement in a typical exec. > I similarly "always" capitalize REXX Key words, to save REXX from > having to spend cycles actually FOLDING then up. It's been years since I wrote any REXX on a mainframe, but I know I didn't uppercase my code back then ... and a quick look at current manuals shows sample code is sometimes in uppercase, and sometimes mixed case. Is this idea that uppercase REXX is more efficient something that everyone here accepts? -- Jeremy Nicoll - my opinions are my own. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN Confidentiality notice: This e-mail message, including any attachments, may contain legally privileged and/or confidential information.
