For the above code $regex get the input file name only. So you not able get the desired output. You must assign the third argument as $regex.
I slightly modify your code. Try this
Code:
die "Usage infile outfile reGex" if @ARGV != 3;
($regex) = $ARGV[2];
open(F,$ARGV[0]) or die "Can't open";
open(FOUT,"+>$ARGV[1]") or die "Can't open";
while (<F>)
{
# $_ is a default variable
# if your regex match the line you get the line into $ARGV[1] file
print FOUT "$_" if ($_ =~ /$regex/);
}

shcomp
SHCOMP(1) Korn shell utilities SHCOMP(1)NAME
shcomp - compile a shell script
SYNOPSIS
shcomp [ options ] [infile [outfile]]
DESCRIPTION
Unless -D is specified, shcomp takes a shell script, infile, and creates a binary format file, outfile, that ksh can read and execute with
the same effect as the original script.
Since aliases are processed as the script is read, alias definitions whose value requires variable expansion will not work correctly.
If -D is specified, all double quoted strings that are preceded by $ are output. These are the messages that need to be translated to
locale specific versions for internationalization.
If outfile is omitted, then the results will be written to standard output. If infile is also omitted, the shell script will be read from
standard input.
OPTIONS
[D dictionary] Generate a list of strings that need to be placed in a message catalog for internationalization. [n noexec] Displays warn-
ing messages for obsolete or non-conforming constructs. [v verbose] Displays input from infile onto standard error as it reads it.
EXIT STATUS
0
Successful completion.
>0
An error occurred.
