i'm playing a bit with scpu stuff atm and noticed some things which i think cant do with ca65, but which are used frequently in sources i check so it might be nice to be able to do this in ca65 aswell :=) 1) getting the MSB of a 24bit value.... something like the > operator but returning the upper 8 bits of a 24bit range instead. 2) forcing 16bit absolute opcodes with 8bit arguments.... ie if i wrote "lda 2" and wanted it to assemble the 3-byte code. (this one would be nice not only for 65816 code :=)) 3) like 2), but for 24bit addresses. this one is kindof really needed for native 65816 programming, else its kindof tricky to work with the first 64k segment :) the scpu assemblers i have checked solve 2) and 3) by certain prefixes/operators to the actual expressions, might be worth considering something simelar. gpz ---------------------------------------------------------------------- To unsubscribe from the list send mail to majordomo_at_musoftware.de with the string "unsubscribe cc65" in the body(!) of the mail.
