Hi, Im new to Perl and am trying to write a script to execute .bat files every 2 seconds. Im able to do it, as long as the file name is file1.bat, file2.bat, file3.bat etc where 1, 2, 3 etc are the variables. This works fine, but when I try to make the name "file" also a variable, I get an error "unknown file", apparently because when I try to concat the first string (in this case either "file" or "text" or "xyz") with the 2nd string (which is a number). The end result needs to be either file1.bat, file2.bat.... or xyz1.bat, xyz2.bat etc. where the character part of file name remains a constant but the number changes. Could anybody help pls. Here is the script 
print "Enter the number in the first batch file:\n";

$f=<STDIN>;

print "Enter the number in the last batch file:\n";

$l=<STDIN>;

for ($i=$f;$i<=$l; $i++)

  { 
    
     $t="file";  
     $concatfile=$t and $i;     
     $file="$concatfile.bat";
     system($file);
     sleep(2);


  }
