in reply to Symbolic references disallowed

A more typical way to handle this would be to say

sub cfgToARRAY { my ($cfgfile) = @_ ; open(OUTPUT, "<", $cfgfile) or die "Can't open $cfgfile: $!" ; my $input ; my @array; while ($input = <OUTPUT>) { chomp $input ; push (@array, $input) ; } close(OUTPUT) ; return(@array) ; } ### my @TEST = cfgToARRAY("/informatica/scripts/arrayDisplayCDCWFs.cfg");

instead of specifying the name of the output array as an argument to the subroutine.

(Upd: changed @OUTPUT to @TEST, 'cos that's what I actually meant to type in the first place (to match the name chosen by the OP) )

    A more idiomatic way to handle this would be to say:

    sub cfgToARRAY { my ( $cfgfile ) = @_ ; open my $OUTPUT, '<', $cfgfile) or die "Can't open $cfgfile: $!"; chomp( my @array = <$OUTPUT> ); return @array; } ### my @OUTPUT = cfgToARRAY( "/informatica/scripts/arrayDisplayCDCWFs.cfg" + );
