Cursor Progression and Subfiles

For RCD context, valid values for tabbing sequence number are 0 and 1.

Value 0 means that no specific tabbing requirements are to be generated and the cursor should progress to the next field in the same subfile record.
Value 1 means that when TAB is pressed in the indicated field then the cursor should advance to the same field in the next subfile record.

All functions are created with default tabbing sequence numbers of 0 to indicate default tabbing: left to right, top to bottom.
