A newly-found RCG bug has been submitted as Bugzilla bug #415 to document recent findings in SUS that indicate three different file-name structures are created by the latest RCG code (2.5.1) to generate the generic MEDM screens. In the local directory, '/opt/rtcds/lho/h2/medm/', the RCG-generated MEDMs are written and sorted based on the individual model's name.

As an example, the directory for the H2 SUS ITMY ('/opt/rtcds/lho/h2/medm/h2susitmy/') generic MEDMs contains file-names of generally two structures:
1.) H2SUS_ITMY_* 
and 
2.) H2SUSITMY_ITMY_* 

A third structure was recently discovered:
3.) H2SUSITMY_*
(Note the difference between (2.) and (3.) is the second "*ITMY*" is missing.) 

This third structure seems to only apply to the ADC, DAC, GDS, BIO, and ALARM MEDMs.
