The size is constant, and is known at compile time. If the size is 1 to 4,096 bytes then you get a series of MVCs, not a loop.

Instead it looped 303 times, then did another MVC of 256 bytes. > Is the size a constant or a variable? That may avoid treating the multiple-of-256 (considered unlikely?) as a special case. If the size is 256 bytes or less, does it execute the loop zero times then then move the rest at the end? -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
