RTI/R-T-I/ interj. The mnemonic for the `return from interrupt' instruction on many computers including the 6502 and 6800. The variant `RETI' is found among former Z80 hackers (almost nobody programs these things in assembler anymore). Equivalent to "Now, where was I?" or used to end a conversational digression. See pop; see also POPJ.
