Hi Clint,
There are a couple of ways to do this in the IDE (in VT 1.7). But I just
noticed a bug I need to fix with the #ifdef / #else / #endif logic.
1. You could define a linker region that is the exact size you want, then
allocate only the code you want in that section.
Linker script:
CODE NAME=some_name START=0 END=255
CODE NAME=.aseg START=256 END=2FFFh
ASM file:
some_name org 0
jmp somewhere
lxi hl, some value
;etc.
; Now switch to the
.aseg org 256
lda 14
; Do something useful
2. You could use the '$' operator (I believe. I will test this, but it
should work)
.org 0
; Add some code here
#if $>255
#error "Code is too big!"
#endif
Documentation is one of the big tasks I have to tackle. For now, Q/A on
this list is the only option.
