Come from

A semi-mythical language construct dual to the "go to"; "COME FROM" would cause the referenced label to act as a sort of trapdoor, so that if the program ever reached it, control would quietly and automagically be transferred to the statement following the "COME FROM". "COME FROM" was first proposed in R.L. Clark's "A Linguistic Contribution to GOTO-less programming", which appeared in a 1973 Datamation issue (and was reprinted in the April 1984 issue of "Communications of the ACM"). This parodied the then-raging "structured programming" holy wars (see considered harmful). Mythically, some variants are the "assigned COME FROM" and the "computed COME FROM" (parodying some nasty control constructs in Fortran and some extended BASICs). Of course, multitasking (or nondeterminism) could be implemented by having more than one "COME FROM" statement coming from the same label.
