During the development of the encoder before all of the routines were implemented, it was necessary to have a has operand flag in the table entries for codes that have an operand. This is no longer necessary as the equivalent can now be determined by whether the code has an operand text or an encode function pointer.
The has operand flag was removed from the table entries of these codes. A has operand table access function was added that returns whether the table entry of the code has an operand text function. The tests for the has operand flag were replaced with this new function or use the presence of the operand text or encode function pointer (by using the table access functions for these).
The program model operand text function is also no longer needed, which had special allowance for whether there was no operand text function for a code with the has operand flag. The encode routine also had special allowance for this same condition, but this is also not necessary since all codes with operands have an encode function.
