I don’t understand what the statement “QSAM does overlapped I/O automatically”
When I do a qsam get the physical I/O is for 1 block every get just ups a pointer BSAM allows me to do multiple Reads each with their own DECB So I already initiate lots of physical I/O mainly because I have lots of records or blocks I find it hard to believe that a qsam get does anything more than read 1 block Thanks > On Mar 20, 2021, at 2:49 PM, Binyamin Dissen <[email protected]> > wrote: > > On Fri, 19 Mar 2021 14:09:59 -0400 Joseph Reichman <[email protected]> > wrote: > > :>When doing overlapped I/O is there a way to tell if the I/O had completed > on the subsequent reads > > :>I check to see if the first fullword has been populated by the BDW > > Did you try without overlapping I/O? > > Post the code. > > -- > Binyamin Dissen <[email protected]> > http://www.dissensoftware.com > > Director, Dissen Software, Bar & Grill - Israel > > ---------------------------------------------------------------------- > For IBM-MAIN subscribe / signoff / archive access instructions, > send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
