in your line:
`$MODULE::PROGS/variable_setup.sh $MODULE::PROGS/myscript.php 'data=$_
+[1]' > $file$_[1].$ext`;

you are single quoting the data=$_[1]. Perl will not interpolate $_[1] when wrapped in single quotes.It won't interpolate any variable inside single quotes for that matter.

    Hello

    I don't think this statement is 100% correct. Perl won't interpolate between single quotes when assigning to a variable. However, if the single quotes are inside double-quotes or a set of backticks, it will interpolate. See the following.

    my $x = "this is the x variable";
my $y = 'single quote of $x';
my $z = "echo '$x'\n";

print $x, "\n";
print $y, "\n";
print $z;

print `echo '$x'`;
print `$z`;

__DATA__
this is the x variable
single quote of $x
echo 'this is the x variable'
this is the x variable
this is the x variable

    note that the assignment to $z does interpolate $x, as does the backtick call to 'echo'

      I stand corrected. You are absolutely right.

      Thanks!
