HRD+DM780

Since 2009 I have been using a free version of HRD v5.24.0.38, recently I have become interested in the RSGB Data contests, and wanted to use the macros in DM780 for contesting, try as I may, I cannot figure out, how to edit the macros for what I require ?

Has anyone any advice please ?
