(_Ropnfbk(openFile))->pgm_record_len will give you the record length for the
_RFILE * open file handle (pOpenFile in my example).
As for more info, check out the following manuals:
"ILE C/C++ Run-Time Library Functions"
"ILE C/C++ Programmer's Guide" -- for some reason IBM puts it under
Websphere Development Studio category
There are other manuals I use, but these should suffice I think.

Subject: Re: [C400-L] Question about _Rreadn C function
How do you know what the record length is?
I don't know ahead of time what file I'll be opening. I suppose I
could use an API call to determine what the record length is, but is
it already there somewhere?
Perhaps in _RIOFB_T or _RFILE?
Speaking of _RIOFB_T and _RFILE. Is there anyplace in the manual that
gives more info on what is contained in these two structures? The
names of the subfields just don't seem to be enough in some cases.
