...tion". For example, think about branch offsets and immediates. Most architectures have some limits about how long branch offsets or immediates are, and a short branch offset may use TOTALLY DIFFERENT instruction encoding than a long branch offset. Do you really expect that the user says "jnel" for the long form of the "jne" instruction? And "jnes" if you want the smaller/faster/simpler 8-bit version? No sane person actually wants that, and no modern assembler does that (although I can remember ones that did - ugh). You write "jne target" and depend on...
