instruction code Search The instruction code 'Search' is an instruction code of the transsmt instruction set that reads in the sequence of 'Nop' instruction codes that follows it, and searches for the location of a complement template (e.g., B:C:D -> D:A:B) in a digital organism's genome. If the complement is not found, a value of 0 will be pushed to the top of the B stack. If a complement is found, the distance between the current instruction code being executed and the beginning of the complement will be pushed onto the B stack, the size of the template will be pushed on the A stack, and the flow-head will be moved to the end of the complement template.
