- -- enumeration type. The table is an array whose index values are 'Pos
- -- values and whose values are access to strings which are are the 'Image
- -- values. Last_Pos is the last index in the table for the enumeration
- -- type. This function will search the table looking for a match against
- -- Str, and if one is found the position number in the table is returned.
- -- If not, Constraint_Error is raised. Str may have leading and trailing
- -- spaces and may be in upper or lower case.
