Hi all, I want to set up a two dimensional array hold start and stop positions. There are 8 rows and two columns (although there may be more rows in future). I have defined my array as:
my @Column_Info = { [ 1024, 1067 ], # Column 1 start stop
[ 1068, 1093 ], # Column 2 start stop
[ 1094, 1137 ], # Column 3 start stop
[ 1138, 1163 ], # Column 4 start stop
[ 1164, 1207 ], # Column 5 start stop
[ 1208, 1233 ], # Column 6 start stop
[ 1234, 1277 ], # Column 7 start stop
[ 1278, 1321 ] }; # Column 8 start stop
When I try and use the array
my $StartPos = $Column_Info{$Count->[0]}; # Slot to start at
my $Pos = $StartPos; # Slot to start at
my $EndPos = $Column_Info{$Count->[1]};
open(IN,"cat /tmp/show_library.$$|");
while (<IN>) {
$_ =~ s/^ //;
while ($Pos <= $EndPos) {
if ($Pos == 1024) {
<snip>
I get the error
Use of uninitialized value in numeric le (<=) at ./show_library.pl lin
+e 143, <IN> line 69.
Use of uninitialized value in printf at ./show_library.pl line 140, <I
+N> line 70.
How do I correctly set up and reference this array?
TIA

PS: I have another question about returning a single dimension array from a subroutine but that can wait until later...
