    May I suggest something like this to read your lines of text:

    use feature ":5.14"; use warnings FATAL => qw(all); use strict; use Data::Dump qw(dump pp); sub readFile($) {my ($f) = @_; $f or die "readFile: No file specified"; open my $F, "<$f" or die "Cannot open $f for input"; local $/ = undef; <$F> } print readFile("readFile.pm");

    Produces:

    use feature ":5.14"; use warnings FATAL => qw(all); use strict; use Data::Dump qw(dump pp); sub readFile($) {my ($f) = @_; $f or die "readFile: No file specified"; open my $F, "<$f" or die "Cannot open $f for input"; local $/ = undef; <$F> } print readFile("readFile.pm");
      Hi,

      Thanks for the help...i was successfully able to finish it...

      i have one more doubt..

      say my code is          F$SFH FIRST,SC==H'160',        COMMENTS                    *   i need to replace ',*' instead of ", K.160 LESEN *" so that my code looks like F$SFH FIRST,SC==H'160',*

      I tried using substitution function.. but i dont know where i am going wrong,. please help me in this... my code looks somewhat like

      $a = F$SFH FIRST,SC==H'160', K.160 LESEN +* $a =~ s/\,[\s]*\*/\,\*/;
