but unable to print it to the a outputfile

It works for me at my unix prompt. It creates "outputfile.log" with these contents:

aaa,1 bbb,2 ccc,3
SUCCESS aaa : a 3 : 1 bbb

It also prints this output with warnings:

aaa,1 bbb,2 ccc,3
ac 1,a 3,b 2,c
Argument "1 bbb" isn't numeric in numeric eq (==) at z line 20, <FHAC>
+ line 1 (#1)
    (W numeric) The indicated string was fed as an argument to an oper
+ator
    that expected a numeric value instead.  If you're fortunate the me
+ssage
    will identify which operator was so unfortunate.

readline() on closed filehandle FHAC at z line 20 (#2)
    (W closed) The filehandle you're reading from got itself closed so
+metime
    before now.  Check your control flow.

SUCCESS aaa : a 3 : 1 bbb

Please edit your post using code tags around your code and data. See Writeup Formatting Tips. Also post the output and any warning messages you get.

Update: simplify your code to see if you can write to a file, and use autodie:

use strict;
use warnings;
use diagnostics;
use autodie;

open( OUTFH, ">outputfile.log" );
print OUTFH "here is some output\n";
print OUTFH "here is more output\n";
close(OUTFH);
