Decided to give some of the code from the CPearson site you suggested a
try.
The following, slightly modified code, ran without error, but failed to
delete any code.
I am trying to delete code from a Sheet module (in another book) - at
first I thought maybe I couldn't deleete from a sheet, so I imported
another code module and tried - didn't delete anything from any modules.

ThisWorkbook is running the code to delete code from another workbook - is
that possible?

The code does work on ThisWorbook - was able to delete code from a book
running the code.
Is it possible to delete code from another book?
