With this change, would it still be wise to initialize data pages as 0? Cause then you may have to SET a lot of VALs through the code pages first.
All data in the VM would be expected to be zeroed prior to it being called and I've also specified that the start of the data area (for constants) could be provided with the AT creation tx.
Also I have now added "indirect assignment" and "indexed indirect assignment" op codes so that if such initialisation was required then it would not take many op codes to do it.
