Re: How to get system -function negative return value?

Maybe this helps:

The return value is the exit status of the program as returned by the [id://perlfunc:wait|wait()] call. To get the actual exit value divide by 256. See also exec.

See perldoc -f system

See also Perl 5.8.4 perldoc system where the new page says: "To get the actual exit value shift right by eight (see below)."

Thanks, but I exactly ment already divided value :-( Code: `my $return_value = system("test.exe something");` [download] returns 0-65280, negative value is always 65280 and when divide it `$return_value = $return_value/256;` [download] it returns naturally 0-255 Maybe I should use some other function. Any suggestions?	[reply] [d/l] [select]

As I said in another post: `$ perl -wle 'print unpack c => pack C => 65280 >> 8' -1` [download] Abigail	[reply] [d/l]
