Line 1,418:
RESULT is set or dropped after a CALL to a subroutine:
It is assigned the value given in the RETURN statement
or it is dropped when there was a RETURN without expression. (some REXX implementations set RESULT also upon return from a function invocation - see version 1 and the Discussion)
SIGL is set when control is tranferred within the REXX program.
