Perl script 'system' linking to local shell script not working

Trying to figure out why this works:

printpwd.pl
Code:
#!/usr/bin/perl
use CGI::Carp qw( fatalsToBrowser );
print "Content-type: text/html\n\n";


$A = system("pwd");
$A = `pwd`;
print "$A\n";

^^actually that works/breaks if that makes any sense.. i get the working directory twice but when i comment out the second variable declaration $A = `pwd`;.. it prints out the success 0. Smilie But at least it printed something out from the cl. Now this confuses me...


hellow.pl
Code:
#!/usr/bin/perl
use CGI::Carp qw( fatalsToBrowser );

print "Content-type: text/html\n\n";

system("hellow");
 
open(HTMLFILE, "hellow.html") || die "
  <center><H3>Sorry, I cannot open HTML pollfile.</H3></center>";
while (read(HTMLFILE, $buffer, 16384))  #Print the Poll HTML file
{
    print $buffer;
}
close(HTMLFILE);

hellow.sh
Code:
#!/bin/sh

echo "</head>
<body text="#FF0000" bgcolor="#000000">
<b>TEST</b>" > hellow.html


The second pair of scripts, when i run hellow locally it works fine generating the html fine but when i remove it and try to have it called from the perl script, perl doesn't err on line 6, it complains of line 8??? grrrr Smilie
