Access specific macros

[autodesk]

2 parts for this question:

- any idea of how I can access a number of macros programatically? for example, i want to access all macros that start with the letters "FAILED".

- I started to write a script to do that, however when I try to access the property macros._NewEnum() I get the following error: "Invalid Character". I think for some reason it does not like the underscore (_). Any suggestions?

Thank you,
Nabil
