no good.
If I understand what your saying, then GW and IZ are both trying to use
the same space in the ZShell string to hold their interupts. If that is
true, is it possible to adjust the tibasic install program to _add_ 600
bytes to the _current_ length of the string, instead of trying to just
add 600 bytes on to 1206? I would assume GW references fixed mem
locations, where it stores it's interupts in ZS, so to make a tibasic
install program which would allow GW to install it's interupt space
_after_ the entire ZS variable (including whatevver else is using that
space), it would also require an ASM program to change the fixed mem
references (chenge the offset) in Game Wizard (where it calls it's
ints). But then again, the GW string would be moving around in memory,
so the other ASM program couldn't write to it.... Ahh...another idea: =
there could be a choice in the actual GW program, which would allow you
to enter an offset (that would be reported by the tibasic install
program), which would update the fixed mem calls...
If that didn't make sense, well, email me...
