Hello
Thanks for your help on my last question: it has really helped me could you explain me why the glob function does not seem to work in the following case ? Thanks

The entry files of my code are files whose name are M4_0_***.txt M4_1_***.txt M4_2_***.txt M4_3_***.txt until M4_50_***.txt Here is the programm: 
use strict;

my $target="$ARGV[0]";
my @M4;
@M4 = glob('M4_${target}_*');
print STDOUT "the files in M4 are @M4";

[download]

the result is : "the files in M4 are M4_$target". It does not seem how to replace the variable by its value. Could you check where did I go wrong ? Thanks
