in thread Checking value of an extracted variable

My code is shown below. After locating the keyword(stored in $first) I need to check the value of the variable stored in $first. $first = SEL_BLOCK. But I need to check the value of the SEL_BLOCK. How can it be done?

open(OUT,">Output.txt") or die "Can't open output.txt for writing:$!\n +"; open(IN, "<Input.txt") or die "Can't open input.txt for reading:$!\n"; @array = <IN>; foreach $line (@array) { chomp ($line); if ($line =~ /^OPT:/) { $var = $'; @param = split / /, $var; $first = $param[1]; print "$first\n"; if ($first==1) { # This is not working as desired $start = 1; } else { $skip = 1; } } elsif ($start == 1 || $skip==1) { if ($line =~ /^]/) { $start = 0; $skip = 0; } elsif ($skip == 0) { printf (OUT "$line\n"); } } else { printf (OUT "$line\n"); } }

    I also like to point out that in the input file the keyword will be declared as below
    Input.txt(input file) OPT: SEL_BLOCK [ some text to be copied to output file if SEL_BLOCK = 1 ]

    SEL_BLOCK will be defined in a config file which can be included in the perl script. The script will have visibilty of the value of SEL_BLOCK and take appropriate actions(copying contents from input to output file).

[ambrus]: the directory structure may be 1, 2, or 3 deep, it may have spaces in the filename or not, it has dates in various format, different keywords for the same meanings, and the dates and other keywords are assembled in various ways.
[Discipulus]: no ambrus by specification i mean for example license per core instead of per socket, so fields are different
