COME FROM n.
A semi-mythical language construct dual to the `go to'; COME FROM <label> 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. Lawrence 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, multi-tasking (or non-determinism) could be implemented by having more than one COME FROM statement coming from the same label.
In some ways the FORTRAN DO looks like a COME FROM statement. After the terminating statement number/CONTINUE is reached, control continues at the statement following the DO. Some generous FORTRANs would allow arbitrary statements (other than CONTINUE) for the statement, leading to examples like:
DO 10 I=1,LIMIT
C imagine many lines of code here, leaving the
C original DO statement lost in the spaghetti...
WRITE(6,10) I,FROB(I)
10 FORMAT(1X,I5,G10.4)
