So... if I was crazy and wanted to implement an IM2 routine.... how do you think I should do it?
Most of my attempts to put the 257 byte data block in memory have failed spectacularly. I think using ORG in an asm statement tends to upset the compiler; but the thing about setting up interrupts is we NEED to put a 257 byte vector table into a very very specific location in memory, and then need to ALSO have the actual interrupt service routine in the specific place that the vector table points to.
*ponder*
I suppose we could use DIM variable @address to force the issue with an array?
On the whole though, this fixed location code isn't really supported by the compiler at this time. How could we work around it?
