Many a machine running DOS and later VSE had 1 Meg memory. In 1987 we ran an HDS clone with 1 Meg of memory. Two CICS regions. It was flat out most of the time and compiling in prime time was largely verboten.
I convinced my manager if we could get more memory it would alleviate some problems. When we went to 2 Meg it flew (like a turkey). We seemed to a manage a whole savings and loans application with that and less than 3 GB of dusk. On Thu, Jan 17, 2019 at 9:37 AM Lester, Bob <bles...@ofiglobal.com> wrote: > Hmmmm.
