Regardless of the instruction used to load the source register, CVD treats it as a signed F-word. So any value with bit 32 (high-order bit of lower half) on will be converted to a negative PD number. So,
CVD R1,DWORD IF LTR,R1,R1,M AP DWORD,=P' 4294967296' ENDIF The modern ways are much better, but the above is what worked pre-21st Century. sas On Thu, Jan 20, 2022 at 3:17 AM Abe Kornelis <a...@bixoft.nl> wrote: > Dave, > > your initial request was for conversion of an unsigned 32-bit binary value. > > The LGF you are using does sign extension...
