[Coco] POKE for WIDTH 80 ?

[Stephen Pereira]

Hi Dave,

Thanks very much for your advice.

I am thinking that overall it will be much easier to remember to do a WIDTH 80 command just prior to LOADM”COLOR4TH.

Thanks very much to all who’ve offered their thoughts!

The 40 & 80-column text modes use 'extended' memory so as not to impinge upon the memory that is available for BASIC programs.  More than just a single 'POKE' would be required to configure the hardware for this to happen.  However, I *think* that you could probably POKE &HE7, 2 and then press the RESET button and BASIC would take care of it for you.  I'm not sure on this since I don't have my CoCo in front of me right now.  It is this flag that keeps BASIC from reverting back to its standard 32-column display when you hit reset.
