Issue
In Vista / Menta 5.1.4 it is possible to have illegal characters such as spaces or - in the program specification name of a Menta file. This will cause this $.mta file to fail when transferring to the Vista DB inside of the system plug-in. It will also cause a Xenta controller to never come online if installed in a Vista Classic DB.
Environment
TAC Menta 5.1.4
Cause
When leaving the program specification blank in a 5.1.4 Menta file, it will automatically be filled in with the name of the entire Menta file when it is saved for the first time. So if you do not fill in the program specification and name/save the Menta file "AHU-1," the program specification will be filled in with AHU-1. This "-" in the AHU-1 is not a legal character and will not be accepted within the Vista DB or the system plug-in.
Resolution
When creating a Menta file for the first time, always remember to set the program specification to a name and without any illegal characters (maximum 12 characters). Once you are in the program specification name editor, it will let you know if you have entered proper syntax.
