[Coco] Another FORTH

[Kandur]

Along with  Willard Goosey in 2005, I'm asking,
"Frank Hogg had a FORTH system... 
I know he dumped all his old FLEX stuff into the PD, what about his coco stuff?"
I paid good money for Frank's FORTH for the Coco. It was worth every penny of it.
Just an example, in the insert mode, the cursor became a vertical line | positioned between 2 characters where the new character(s) would be inserted. 
Just curious, was such a scheme implemented somewhere else too?
The screen layout and the color scheme was also exceptional.
Wish, I could find it!
