I am using the MS-DOS Aztec cross-compilers to create PRODOS SYS
files for the //e.  My only problem so far is that I cannot figure
out how to get the program to run in 80-column mode.  PRODOS boots
into 80- column mode and presents me with a menu, but when I select
my program for execution it runs in 40-column mode.

I didn't know that ProDOS could boot into 80-column mode; I always
thought the startup program had to do that. Here's my take on how a
system program might initialize 80-columns, as suggested in the ProDOS 8
Technical Reference Manual:


PRODOS8 apparently does, at least the disk image I have does.  Thanks
for the TRM.


Are you sure it isn't the STARTUP program setting 80 columns?
PR#3 is a very common component of many STARTUP programs.
