For the archives, I found answers to my issue.
1. The “/bin/c89” executable on my system was an obsolete version; I had to
add the “/usr/lpp/cbclib/xlc/bin” directory to my $PATH to get the correct
version
2. My translation of the sample Rexx script to a shell script incorrectly
left the flag parameters on the c89 command line inside apostrophes, which
prevented c89 from actually seeing them correctly as arguments. I had to
remove the apostrophes and add “backslash-parenthesis” escapes for the LANGLVL
option value
The now-working shell script line to run the c89 command is:
c89 -oceasamt -v -g
-Wc,LP64,SHOW,SO,AGGR,XREF,NOOFF,NOOPT,EXP,LIST\(./\),SSCOMM,DLL,STA,LANGLVL\(EXTENDED\),WARN64
-Wl,LP64,map,xref ./ceasampt.c /usr/lib/ceasapit.x

Subject: Re: c89 syntax errors despite using the SSCOMM compiler option
Could be a code page issue. USS users guide says
The LC_SYNTAX environment variable
The POSIX portable character set has 13 characters whose encoding might
vary on different EBCDIC code
pages:
Right brace (}) Left brace ({) Backslash (\) Right bracket (]) Left bracket
([) Circumflex (^) Tilde (~) Exclamation point (!) Number sign (#)
Vertical bar (|) Dollar sign ($) *Commercial at-sign (@)* Accent grave (`)
ls -T ccc.c will show you the code page.
IBMUSER:/u/ibmuser: >ls -T ccc.c
- untagged T=off ccc.c
I compiled a line line C program with // @
and it did not have any problems.
