Hi,

I guess it's accepted and expected, but I can't find any documentation that explains this differing behaviour.
Without the enclosing parens, the exit function behaves as I expect - otherwise the specified value is apparently ignored, and the exit call defaults to exit 0. 
D:\>perl -wle "`exit 1`; print $?;"
256

D:\>perl -wle "`exit(1)`; print $?;"
0

D:\>perl -wle "`exit 2`; print $?;"
512

D:\>perl -wle "`exit(2)`; print $?;"
0

D:\>perl -wle "$x = 1;`exit $x`; print $?;"
256

D:\>perl -wle "$x = 1;`exit($x)`; print $?;"
0

What am I failing to understand ?

I'm seeing this behaviour on Windows 11 with perl-5.38.0 and perl-5.39.4. That's the only testing I've done.

Cheers,
Rob

In reply to "exit 1" and "exit(1)" are apparently not the same by syphilis
