Searching for the keyword "function" will most likely result in hundreds (thousands?) of false positive hits since that keyword is present throughout object source code, as is "subroutine" (just typically not as frequently as "function").

- For external function declarations, I suggest instead searching for "library " (the word library with a trailing space included).

- If the app runs other programs, search for "run(" (or "run (" depending on the coding style used) if the PowerScript Run function is used to execute them.

- If the app uses OLE to interface with OLE server applications such as Excel or Outlook, search for the PowerScript function names that begin with "connectto".
