This data type is used for entities that describe the letters that will make out the start of the names of all global variables that will be generated by MSM-Workstation for the data structures related to the current window.
Data of this type must meet the syntax of a name (possibly starting with a percent sign), and may not exceed 5 characters. In addition, names must be uppercase only, and names that start with the characters %MDS are prohibited.
Names that start with the characters %BLD and BLD are reserved for use by the ViEW/Builder.
