Right...
Tried some things this morning.
It's working, but...
I'm pretty sure the use of BASIC v 1.29 helps, but looks like it needs the 1.4 system file as well. I'm pretty sure that the 1.4 system was the system that BASIC 1.29 would have come with, so that's consistent at least.
If I use the 1.4 system, with 1.29 BASIC, on A:, then it seems to work fine. But on B:, which I would prefer, seems NOT. But there are two sides to the 'boot' disk, A and B, and we don't know why the difference, so I'm wondering if part of the difference regards using A: or B:, so I need to get both versions of EXBASIC (which ARE slightly different) ready to try and check this out.
This just leaves the problem that I have the uIDE drives, and to support this I need a later version of the system. 1.4 will NOT work for this. I'll try the 1.07H just in case, but I'll not rely on that. This isn't a disaster, I keep a boot disk for 1.4 anyway for something else (the FORMAT prog for my 5.25" drive has a problem with the later systems). Just an inconvenience.
I'll see how it goes.
However, the EXBASIC system does work, given the RIGHT environment. Have to play about, and see what can be done with it.
