The expected data type member of the Expression Info structure was initialized during table initialization based on the type (operator or function), number of operands and data types of the operands. This variable was moved to the table entry so that the preset expression info instances are not modified. This resolved the issue with the REPEAT$ function. An initialization value needed to be added to all of the table entries, a drawback of the current flat table entry array (though this will be changed in time). The default data type value was used.
This is about the end of the preliminary changes for the table. The next post will begin to describe the new table design. Since the changes will be significant, an attempt will be made to transition to the new design in a series of smaller changes. The movement of the expected data type could be considered the first of these changes.
