; A string whose text spells an instruction.
;
; The quotes are gone by the time the assembler looks at a token, so a string reading "ADD"
; used to be assembled as the ADD instruction - which failed with "attempting to assemble
; outside the Program Segment", a message about a mistake nobody had made. Mnemonics match
; without regard to case, so "or" and "and" were caught by it too, and those are ordinary
; enough words to want in a message.
;
; Correct output is:
;   ADD OR and NOP
