Hi, Sorry again for coming back with a similar bit of code. I get the message: Use of uninitialized value in substitution (s///) at transform.pl line 19, <INPUT> line 78. 

if ($line =~ /^%(.{1,100})$/){
 s/\s//g;
 
 $name = $1;
 print "EEEEEEEEEEEEEEEEEEEEEEEEEEEE: $name\n";
    }
    
    $outfile = "outfile['$name'].txt";
    open (OUTFILE, "+>>$outfile");

I would like to remove white space for the variable $name that is used to name the output files. Can any monks offer support and guidance to a man who is new to the cloth?
