Memory Map - britlion - 03-14-2010 It would be nice to be able to map the program produced in memory, work out where it is - and optionally, where gaps are (very useful for IM2 stuff) so that the gaps could be used. Even if only as buffer memory for other functions. Re: Memory Map - boriel - 03-14-2010 This has already been requested by LCD, I think. But there are two things to keep in mind: This applies mostly to Speccy, not to a generic machine architecture. This is very low level (not high level, like BASIC). So perhaps this should go in the assembler (zxasm). As far as I know, no compiler does that currently. The closest approach is the INTERRUPT subroutine in Borland Turbo Pascal, as far as I can remember. Since creating an IM2 routine does not imply the whole routine should go in a memory zone (a single JP in that memory zone should be OK), this could be left to the compiler. Anyway, a Memory Map Report (as LCD suggested) would be nice. You can later create a routine at empty places with ASM + ORG XXX. The best way to do this could be a DIM AT @XXXXX array of bytes, with the bytes containing the machine code, at the moment, I guess. Re: Memory Map - britlion - 03-17-2010 I was also thinking that if we have un-moveable code, it would be good to know whether our main program and includes are overwriting it!
