There are four distinct versions of EDTASM+ and I can't remember you 
saying which you use; EDTASM+ pak (cassette based program), SuperPatched 
EDTASM+ pak (a Rainbow program by Roger Schrag that converts pak to a 
disk only version; no longer runs from ROM pak), Disk EDTASM+ (by Tandy 
for disk and tape, 32 column screen), EDTASM6309 ( my for sale patch for 
Disk EDTASM; many enhancements).

I don't recall if the ROM pak is self starting. If not, then there will 
be differences in use between a Coco3 an older models. Paks are started 
on most units with an EXEC&HC000 unless self starting. The Coco3 
requires Paks be started with EXEC&HE010 to compensate for changes in 
the Coco3 hardware.

Schrag's version should be started on a Coco3 from the 32 column screen 
with a LOADM and EXEC. As written it won't work from a 40 or 80 column 
screen.

The Tandy disk version needs some patches to the DOS.BAS program to 
operate in 40 or 80 column screens and should be started from a 32 
column screen. Do a web search for information on using this version on 
40 and 80 column screens.

My EDTASM6309 will self select a 32 or 80 column screen based on the 
model Coco that runs the program. A Coco3 owner can toggle between the 
40 and 80 column screens at will. If you want to use the options built 
into the DOS.BAS loader, you should switch to 32 columns before use but 
if you configure the loader to auto start EDTASM, switching screens is 
not necessary.
