FOO = ARG(1)
BAR = ARG(2)
SOJACK = ARG(3)
No. That works only for Rexx:
CALL BINTDECR FOO, BAR, SOJACK
Ass opposed to what?
Use PARSE ARG FOO BAR SOJACK, which preserves case.
The parse arg may be better style, but it is fully equivalent to the three
assignment statements. Don't confuse arg foo with foo=arg(1).

I got an off-list note from Sam Golob asking me to submit an actual fix, so
I downloaded CBT 617 to have a clean copy to start from and it is *not* the
source of the program I am using (and complaining about here).
It *does* however have the same bug:
BINTDECR:
NUMERIC DIGITS 20
ARG LITERAL
INTZ = "LITERAL = C2X(''LITERAL'')"
INTERPRET INTZ
...
Ouch! INTERPRET is unnecessary, and perhaps dangerous
because of the possibility of code injection via the value of ARG.
"A little learning is a dangerous thing."
Not sure exactly where to go from here. This misuse of ARG for binary fields
seems to be pervasive! I don't have the time to be "Mr. Fix all the CBT Rexx
misuses of ARG."
They probably expect you to prepare your input with CAPS ON.
If you are using any Rexx code that processes binary data (such as SMF
records) you might want to do a quick FIND on ARG and see if it has the same
problem. Easy to fix:
ARG FOO becomes FOO = ARG(1)
OK.
ARG FOO BAR SOJACK becomes
FOO = ARG(1)
BAR = ARG(2)
SOJACK = ARG(3)
Etc.
No. That works only for Rexx:
CALL BINTDECR FOO, BAR, SOJACK
Use PARSE ARG FOO BAR SOJACK, which preserves case.
