The macro can be run by IDEA 7 and 8. 

Files in 'nm3.zip' must be extracted to drive folder 'c:\ffsnet', because the macro uses that folder.
Create that folder, if you do not have it on your c:-drive.
1. Click 'NM3.exe' or...
2a. Start IDEA 
2b. Select: Tools - Macros - Run; file explorer starts
2c. Select file type: Compiled IDEA macro files (*.ise)
2d. Browse until you find 'NM3.ise'
2e. Select it

The macro cannot be run if 'nm3.txt' is changed in any way. This is to protect you from 
falsified files. 

First run of the macro can fail. So you might need another try to run the macro correctly.

Please, note that you use the macro on your own risk!
