Strange file - only CR as 'end of line'	Can't Post

Hi all

I get a strange text file with only CR as 'end of line', from a source that is unknown to me. I assume it is created by MicroFocus COBOL on Unix server. I am prety sure it does not come from a z/OS mainframe. The records are fixed length and it might be some standard in the originating environment. I do get other fixed length files from that environment but they all have the standard CR/LF or LF.

My question is how could I tell Perl to either view 'CR only' as 'end of line' or break the file to fixed length chunks?

Thank you all

ZA

Found the solution, to use the $/ (use it locally if you do not want major bugs :))

Code

       
 
      my $irs = $/; 
     {#<<<= anonimous 
       local $/ = $irs; #default 
       if (some condition...) {$/ = \229;}   
 
#to allow the program to read normal as well as stupid fixed length 228 + CR characters 
       open (INDEXIN, "$SourceFile")  or die("Couldn't open input file: $!"); 
       while (<INDEXIN>) 
       { 
          chop; #if you want to get rid of the CR  
 
          ... do something ... 
       } 
     }#<<<= end anonimous
