Still working through this, I've posted my code to github: https://github.com/davidshq/pyBASICTools
Right now it:
1. Loads the file into a list.
2. Iterates through each item in the list.
3. If it finds the string "DECLARE SUB" outputs a message to the display.
4. Continues parsing until the entire list (and thus contents of the file) have been searched.
About as far as I'm getting with it tonight...will update as I make more progress. Any suggestions are welcome :)
