I like it. However, COUNT(*) is not one of my own variables and there
is no documentation in Watcom that tells me exactly what is returned:
long, word or byte. However, a little experimenting shouldn't be very
difficult and should tell me exactly what I need to know. Thanks for
the idea.
DM>> SQLINTEGER count;

DM>> SQLINTEGER cb;
DM>> SQLGetData(bstmt, &count, 0, &cb);
Upon re-reading this, I'll have to try it.
