[Coco] Sailorman and DW ??

[Bill Pierce]

Charlie,
It sounds like the first MLprogram it loads wipes out the basic listing or at least it's variable storage. I remember running Sailorman on my old Coco 2, but I don't know if I ever ran it on the Coco 3.
Another problem you may be having is that on a Coco 1-2 the Roms are active, meaning you can't hurt them, write over them, etc. A lot of old Coco 2 programs used the space under the Roms for storage and used flip-flop routines. If you run HDBDOS from disk, then you are copying Rom to Ram and any program using the Rom area for storage will write over the the copied Roms and crash the system. This was the problem with a lot of old Coco 2 programs on the Coco 3 as the Coco 3 runs in all Ram mode so it can patch itself on startup. I once wrote a really nice graphics editor that allowed you to have up to 7 PMode 4 screens in memory by storing them under the roms. When I bought my Coco 3, I was heartbroken that this program would not run any longer.

A follow up to my Sailorman and DW question.

I just found out that if you are using a coco3 with DW the SAILOR/BAS 
program runs and loads the game fine.

So the problem is with DECB1.1 in the coco1 vs DECB2.1 in the coco3.

Still, why will typing the lines in at the prompt make the game run but not 
if they are placed in a program?
