A small part of a change made a few commits ago (see January 10) modified the assign string recreate function where the name of the Equal code is used instead of the name of the assign code. This was done to remove the use of the Assign code enumerator (the Equal code enumerator is used in many places and will be one of the enumerators in the new code type enumeration).
The assign recreate function was modified to also get the name from the equal code table entry. Since both assign recreate functions use the name from the equal code table entry, their table entries no longer need a name, so their names were set to a blank string. The expected test results were updated accordingly.

Table – Code Indexes
Indexes of table entries are used in the program code to represent a table entry of a code. When the program code is read, then these indexes should be converted back to a table entry point, which is then used to access information about the code. These code indexes should only be used in the program code. However, the code indexes have been used throughout mainly within tokens.
As of the last change, they are no longer used within tokens. The only remaining uses are a few code enumerators to get a table entry and some uses within the tester class. The few code enumerators still used but will become code type enumerators when these code enumerators are combined with the type enumerators.
The tester class was using code indexes to determine if define functions contain parentheses or not. When define functions are implemented, their dictionary entries will contain the number of arguments. No arguments will mean that there are no parentheses. Since this is not yet implemented, the code indexes were used temporarily to determine if parentheses were present. The tester class should not be using code indexes.
A new Define Function No Arguments type was added for the three defined function codes without parentheses. The tester routines were modified to use this new type instead of checking for code indexes. There will be an equivalent temporary code type enumerator for this same purpose once the type enumeration and code index enumeration is removed. A case for this new type was added to the translator get operand function at the current Define Function case. With a new type, the expected results for parser test #2 (identifiers) needed to be updated.
