The following code does not give a warning:
CHARACTER(2) FUNCTION ctbgt() RESULT(ctab)
END function ctbgt
Only if one removes either the RESULT or changes CHARACTER in, e.g., INTEGER a
warning is shown.
w/ RESULT and INTEGER:
warning: Function return value not set
w/o RESULT:
warning: Function does not return a value
* * *
Similarly for INTENT(OUT) arguments of procedures:
SUBROUTINE ctbgt(ctab)
INTEGER, intent(out) :: ctab
END SUBROUTINE ctbgt
