Dave, thanks. Yes that does make sense and I appreciate the clarification as to what 'pseudo' means in this instance. I did wonder whether it something like that and whether certain memory locations were used for multiple purposes as in your explanation of REGISTER13 vs DIMSUBSCRIP as well as registers holding a single 16-bit value vs two 8-bit ones. I will have to consider how to lay out the information in my document.
