'===========================================================================
'>Can someone please send me a simple text editor in plain Basic (QBasic or
'>QB45) code. It must have the ability to print on paper, on screen; load
'>files; save files; edit files;; all in a simple code. I am trying to learn
'>this language, but I need some good examples.
'>I will probably use this txt editor for my own purposes and not for any
'>distribution of any sort.

'I never finished this program -- I was adding a cut, copy paste
'feature -- but it is functional. I stopped programming when DOS
'started to ship with a REAL editor, not EDLIN. I used Text Rite for
'years, installing it on every machine I used.

'It runs under QBASIC, QuickBasic, and PowerBASIC. Note: For PB,
'you have to change calls to PCOPY... but that's easy, it's well
'documented in the manual. I've tested it, and it does work.

'If anyone would like to continue the Text Rite challenge (a
'good BASIC editor) let me know. I'd love to see this done, if
'just to prove BASIC isn't a toy.

'Again, I was going to add: CUT/COPY/PASTE, and MOUSE calls.
'I realized AFTER I wrote the code that the menu routines were
'sloppy; I have since re-written them to be more logical. My
'newer (two or three years old!) menu routines are a lot easier
'to read and modify. I switched to TYPEd variables to enable a help
'string for each menu item.

'It's old and ugly, but here goes nothing:
