Hello, I am a newbie in Perl and seeking a help with file open using variables. In below code, I like to use variables X_info, Y_info, Z_info in the file open line so I can only change the variable contents to open a file. Can someone help this? I can't figure this out. Thanks, Steve

use strict;

my X_info = 3;
my Y_info = -4;
my Z_info = 5;

    
###### want to replace 3 with X_info, -4 with Y_info, 5 with Z_info ##

+e have a problem: $!";
     print "It Works.\n"
close (DLOG);
