Gil, Are your questions because you want to use the utilities, or just pedagogical?  :-) -l l4 is compatible with FILEDATA=RECORD, and I think predates it.   It sounds like your issue is that we didn't use the IBM terminology? Unicode conversion errors (UTF-8) print an error to stderr and

Thanks to everyone for their input.  Since I was already using C/C++ I/0 functions to access a card file I thought that it would be simple enough to setup the DD:SYSLIB and that it would actually point me to a DCB address that I could use in my BLDL and LOAD macro(s).  I ended up defining the

IMHO this is not a good idea, because the C/C++ runtime probably did more things than simply construct a DCB and open it; IMO it allocated storage for buffers etc., too. And if you "steal" the open DCB from it, you will leave the C/C++ runtime in an undefined state, at best, even if you plan
