[Coco] Roger Schrag's patches for Edtasm

[Tony C]

Does anyone have documentation on what Roger Schrag's patches did for
Edtasm?
I remember his name/patch from many years ago, but that's it :-)
 Were new commands /features added to Etdasm with this patch?
   It's wierd how one's memory works. Even after 10-12 years of not having
used a Coco, I associated the name "Roger Schrag" with some patch for
edtasm, but that's all I can remember.
However, when trying to load a program from a .DSK image the other night, I
typed load "filename.bas":0 like I had not stopped using the coco :-)
 thanks
