So I have a script that replaces certain strings with other strings identified with a regex and a hash. I have the following problem: The way I have written the script, I break lines into substrings, do the substitution on one part but not the other, and then put them together. this works fine. The problem is, the last string in all these files is on character long... so short that when I try to cut in into substrings, there is a failure. It says: 
substr outside of string at ReturnA/ReturnAReplacer.pl line 90, <IN> l
+ine 8453.

the thing is, I don't care. I realize the last one is always too short, but I want it to go on and deal with the next file anyway. I can't tell it to just ignor the 8574th line because in the next file it might be the 19756th line and so one... forty some-odd files, each with a different number of lines.

Here's the code: 

foreach $file (@infile){
    open(IN, '<', "$file") or warn $! and next;
    open(OUT, '>', $outpath.basename($file))
    or warn $! and next;
            while (<IN>) {
            substr($_,279) =~ s/$regex/$substitute{$1}/g;
            print OUT $_;
            }
                
}
