Obviously once you get into this path there's no use for any of the "official" X-Mem functions, so this is an either/or choice.
Remember: X-Mem files will not survive the use of the X-Regs functions!

The loss of the rest of the X-MEM file functions is a real limitation, especially the ability that I've been using a lot in the past to save/restore a program to X-MEM.
Maybe a possible mitigation would be to use a regular X-M DATA file with all your new functions accessing it. This would be much more flexible than the SEEKPT, GETX/SAVEX sequence, and the user would be able to dedicate part or all of the X-MEM for this purpose.

Thanks for chiming in J-F.
I see what you're suggesting and it's a "compromise" for backwards compatibility; so I'll think about it. So far I wanted to have a separate environment, so to me it is not about mitigation since the goal was never to be compatible with the classic approach. I'll give it a thought, anyway.
