--- Comment #4 from Harald Anlauf <anlauf at gmx dot de> ---
Cases z1, z2 are invalid codes:
ifort:
pr69604-z1.f90(2): error #6579: A dummy argument of a statement function is
invalid in this context. [N]
x(n) = n()
----------^
compilation aborted for pr69604-z1.f90 (code 1)
sunf95:
x(n) = n()
^
"pr69604-z1.f90", Line = 2, Column = 11: ERROR: "N" is declared as the
statement function dummy argument, therefore it must not be used as an external
function name.
f90comp: 4 SOURCE LINES
f90comp: 1 ERRORS, 0 WARNINGS, 0 OTHER MESSAGES, 0 ANSI
Case z4 appears technically valid.
