Hi Bill (or any other C programmer) !
OK, perror("dd:OUTF"); gives me
EDC5057I The open mode string was invalid. Explanation: The mode string
passed to the fopen()/freopen() function was found to have invalid
keywords, combinations, or characters. For example, if you are opening a
ddname, be sure the DISP= specified on the DD statement is compatible
with the open mode you specified. Programmer response: Correct the mode
string and reissue the fopen()/freopen().
I'm not much wiser with this explanation.
I know that if I use only
outf = fopen("dd:OUTF","w+");
and
//OUTF DD DISP=OLD,DSN=SYS2#.C.OUTF
the program executes properly with zero return code.
In this case the OUTF file is on disk with recfm=vb, lrecl=1028,
blksize=6144.
So I'm still in the dark as to how to get this to write to SYSOUT=A.
Regards
Lorne

The "perror" function might give you more information about why fopen is
failing. See above.
