In that case, try:

ctl-opt dftactgrp(*no);

dcl-pr RtvReuse extpgm('QDBRTVFD');
rcvVar char(65535) options(*varsize);
lenRcvVar int(10) const;
qualRtnFN char(20);
formatAPI char(8) const;
qualFileName char(20) const;
rcdFmtName char(10) const;
ovrPcs char(1) const;
system char(10) const;
formatType char(10) const;
errCde likeds(qusec);
end-pr;

/copy qsysinc/qrpglesrc,qusec
/copy qsysinc/qrpglesrc,qdbrtvfd

dcl-ds baseFD likeds(QDBQ25) based(ptrRcvVar);
dcl-ds pFAtrs likeds(QDBQ26) based(ptrPFAtrs);

dcl-ds errCde qualified;

hdr likeds(qusec);

errDta char(256);

end-ds;



dcl-s ptrPFAtrs pointer;

dcl-s ptrRcvVar pointer inz(%addr(rcvVar));

dcl-s qualRtnFN char(20);

dcl-s rcvVar char(4096);

dcl-s theFile char(10) inz('MYFILE');



errCde.hdr.QUSBPrv = 0;

RtvReuse( rcvVar :%size(rcvVar) :qualRtnFN

:'FILD0100' :(theFile + '*LIBL') :' *FIRST'

:'0' :'*LCL' :'*INT'

:errCde);

ptrPFAtrs = ptrRcvVar + baseFD.QDBPFOf;

if %bitand(pFAtrs.QDBBits33 :x'80') = x'80';

dsply 'Reuse on';

else;
dsply 'Reuse off';
endif;
*inlr = *on;
return;

where variable theFile is initialized to 'MYFILE' (real original I know)
and *LIBL is being used to resolve to the file. You can provide a theFile
value in whatever fashion you desire (parm, file,...). Note that there is
no error recovery. Pass it a "bad" file name and you'll just get good old
CPFs and RNQs.

This requires no DSPFFD and subsequent processing so it should be faster
but, as pointed out earlier, there's also nothing wrong with DSPFFD and an
outfile. Just another way to get the job done.

Thanks, but I'd much rather do a query in one step rather than having to
create the data and then query it.

The system catalogs would not have that, as they are very SQL-related,

That rationale is very understandable, but it's not that useful as a
heuristic for predicting what information is *actually* provided in
the catalogs. TABLE_TYPE, FILE_TYPE, SELECT_OMIT, and IASP_NUMBER are
all IBM-i-specific and would not make sense on other SQL-enabled
systems. (Even if you could find a non-IBM platform which has
something analogous to IASPs, chances are they wouldn't *call* it
IASPs. And in any case, this is utterly irrelevant to *SQL*.)

Even something like NUMBER_DELETED_ROWS isn't really relevant to SQL,
and the fact that it's available (via SQL) on the i makes it
oh-so-tantalizingly close to having something which tells you whether
those rows can be reused or not.

Gord, no matter what anyone says, there is nothing wrong with using
DSPFFD to *OUTFILE. I mean, it's definitely worth taking a look into
the catalogs; and worth asking here in case you missed something; and
you did both of those things. But even if you hadn't checked, and gone
straight to DSPFFD instead, I wouldn't fault you for that.
