Not knowing what the utility is and/or how widely it would be used, if you have the space at all, you should go for the full 40 bytes. Otherwise, there will...

I don't think so. There was a great push when the market was flooded with surplus TI parts to swap to the cooler running power supply. It may have been Radio...
Here's the routine from ZT4. It's very fast already but looking at it again now, I think it could be made even faster with a little tweaking. Might give you...
That's fixed easily enough by sampling the keyboard on a timer... Buffer the keys up until the application needs them. That way the application can be doing...

Well, after checking my spreadsheet on VDP usage, I may have the space for 64 bytes per PAB. Which would be 54 bytes for pathnames, more than enough to satisfy...
Adam, There's no point in going over the 40 bytes for full pathname (devicename+sub-directory, sub-directory, etc.+filename) as the Myarc HFDC architecture...
I'll keep that in mind. I don't want to burn data space to store precise address locations for the PAB's, so I was going to just space them equally apart in...
I was wondering about that, is it possible that a new DSR could be made in the future that allows longer path/file names? The only parallel I can think of is...

Dan, There's another problem. Just "modifying" the Geneve Master DSR won't solve the "problem". Any programs, past or present, TI or Geneve that accessed...

Hi Tom, After I read the way I wrote the question, I realized that it could be interpreted as me asking for help to find the answer, instead of posing an...
I'd rather that the PAB's stay in VDP, where they're immediately accessible, and I can load them via a hard-coded PAB as a memory image. Multiple files open at...
