OS_Memory 0 logical to physical

I know it doesn’t support IO memory, which is a right pain, but should it currently support VRAM?

On IOMD with VRAM, converting the logical DA2 address to physical should return &2000000 but instead it returns 0, this seems to be the case right back to when OS_Memory was added. Is this correct? Shouldn’t it return the VRAM base address or is VRAM classed as IO memory?

Works fine for me on 3.7 and 5.x

SYS "OS_ReadDynamicArea",2 TO A
DIM B% 12
B%!4=A
SYS "OS_Memory",0+(1<<9)+(1<<13),B%,1
PRINT ~(B%!8)

I fess up…I was misreading the PRM and converting to pages instead of physical. Sorry for wasting your time.

No problem!
