The Bind attribute merely tells Program Management what mode you want to be called in, it has no lingering effect. What is slow? Compared to what?
I converted a service routine to 64-bit, but it keeps the same interface to its 31-bit mode callers. When called, it cleans up the registers, then switches to 64-bit mode. That is probably typical unless you write a new routine that is expected to be called in 64-bit mode. But you might get a surprise when you LINK to a 64-bit module the first time (S406). sas On Tue, May 5, 2015 at 8:59 AM, Brite < [email protected]> wrote: > We have some assembler programs written in 64-bit mode (using 64-bit mode > instructions) since they allocate storage above 2G line to put some tables. > But we still link-edit them with AMODE 31.
