Poor Man's Spell Checker is a simple spell checking script. It has a medium-sized word list which should be sufficient for most applications that don't require a heavy-duty, industrial-strength, spell-checking monster. The most memory and CPU intensive part of the script is when the word list is loaded into an array from the text file. Although this program is written in VB script you could easily port it to the language of your choice. If you are using PMSC as a web script, there could be a short delay while the word list is loaded into memory depending on the performance of your server.
