So: replace all uses of FLOGR with invocations of the macro (using OPSYN?). The macro uses STFLE to test availability and use then native FLOGR, else falls through to the emulation code? Some degradation of the native FLOGR, but good compatibility.
I don't know where the z9 PoO is, and I'm curious: does the *LOG* imbedded in FLOGR stand for LOGarithm, since the operation effectively finds the integer part of the base 2 logarithm of the operand? -- gil -- StorageTek INFORMATION made POWERFUL ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
