I can not imagine this particular technique being any more error prone than balancing stack PUSHs and POPs.


I would think that the first order of business is to develop your DPTR usage policy to suit your performance (or whatever) requirements, even if it does not use all eight DPTRs, and in fact, even if it ends up using only one DPTR. Then develop the code to implement your policy.

If you have trouble figuring out how to utilize multiple DPTRs to achieve your requirements, then show us your requirements. Or, if you've got a handle on utilizing multiple DPTRs to achieve your performance requirments, but need help managing or keeping track of them, then show us your utilization plan. After seeing either case, we (don't necessarily read 'I', as in 'me', as in 'Dan') should be able to help.
