Populate field with series of numbers computed from separate minimum and maximum fields

I should probably explain what I'm trying to do. Essentially, I'm looking for a more user-friendly way to enter a range of numeric values than having to type each number into the field comma-separated or selecting each value from a multi-value select list. This is particularly important for large ranges.

I suppose the ideal solution would be a CCK option widget that allows the user to simply enter "20-25" in a single field, and have it stored in the database as "20,21,22,23,24,25". I don't think this is possible at the moment which is why I've turned to Computed Field.

I'm not a coder, but I ran into an article here. Obviously the code below doesn't work but could I do something like this?

foreach(range($node->field_value_minimum[0]['value'], $node->field_value_maximum[0]['value'], 1);
{
    echo implode(', ', $aArray); 
}  

The reason I need an array of numbers is so that people can perform a search in Views. For example, if someone searched all nodes that contain the number "23" in a certain field, they wouldn't find my node with the text string "20-25" in that field, but they would find it if it was in the format "20,21,22,23,24,25".
