RE: hash assignment question

[Bradshaw, Brian]

Actually, this is a function that takes a passed in key name and value and
matches them up. the $theName variable is for some presentation code.

I need a list that looks like :

%hash = (
        "field1" => "Bob",
        "field2" => "Smith",
);

I init the hash with an $arr_criteria_hash(); line

As for the for loop, well, I may get that advanced some time. 

Is there an advantage to using for loops over while loops?

What is this ...

---
        sub ShowCriteria { #($theKey, $theValue, $theName) {
                $arr_criteria_hash{@_[0]} = @_[1];
...
        }

All about?? You won't get blank keys. You don't need to create the hash
before you use it, Perl will handle that. You could do it like this

$value = 50;
$hash{"key"} = $value;
$hash{"key2"} = $value;

That will give you a hash which looks like this

%hash = (
        "key" => 50,
        "key2" => 50,
);

To read the values back out of the hash

foreach $key (sort keys %hash) { # The sort will return the keys in the hash
sorted 
        print "$key => $hash{$key}\n";
}


You don't need a while loop to read it.

Using your code, you could do something like

foreach $field (keys %arr_criteria_hash) {
        $newText = " $field like '%$hash{$field}%'";
        ...
        }

But if what you've got is working...
