Number of Data Types Enumerator

Not only does the data type enumerator have the size of enumerator (which needs to be removed before changing to an enumeration class), it also has a number of enumerator, which was placed after the three main data types (double, integer and string).  This enumerator was removed, but is was used to dimension two arrays that needed to be changed.

In the Table constructor, there is a section that scans the secondary associated codes of a main code, the purpose of which is to set the expected data type for the main code.  If the main code has associated codes for both doubles and integers, the expected data type is set to number (for example, the minus operator); and if there are associated codes for all three types (numbers and string), the expected data type is set to any (for example, the plus operator).

This is accomplished by using bit masks where there is a bit for each type (double, integer and string).  For each associated code, the data type of the code is bit-wise ORed together.  After all the associated codes are scanned, the final value is checked to see if it as the two number bits set or all three bits set to determine the expected data type.

Originally, an array of three elements was defined with the bit masks for the three data types.  The number of enumerator was used to dimension this array.  With the number of enumerator removed, this array was replaced with an unordered map, with an initializer list to set the bit masks for each data type enumerator.

The other use of the number of enumerator was in the equivalent data type function of the Table class, which contained an array from data type to equivalent data type, but when the sub-string and temporary string data types were removed, this function ended up essentially just returning the data type passed to it.  In other words, this function is no longer does anything, so it was removed and the one use of it was replaced with the data type (in the LET translator routine).
