Some of Point Beach RO's have curly braces in the RO return value for the units in P/C. Found this on some (5-7) Annunciator RO values. The definition of the return value (multiple return values) uses curly braces so PROMS cannot distinguish between brackets being part of a unit value or part of the format for multiple return values.
Equipment Designation, Main Steam (MS), Annunciators have examples of return values with curly braces. Look at the Referenced Object Definition on the Annunciators tree node for the definition of the return value.
In creating a temporary (meta) file for Complete RO Report, file was sometimes not created anew with the FileMode.Create setting. Changed to FileMode.Append and specifically delete the meta file before calling to generate it.
