QC2.COM is a resident 1-line text editor for AutoCAD.

ALT-E or ALT-R pops it up, when AutoCAD is prompting for 'New Text' (but you
 still have to pick CHANGE and hit ENTER 5 times).
To fix that, TEXTED in the included ACAD.LSP prompts for text entities and
goes to the resident editor, once for each entity.
ATEDIT.LSP does the same for Block Attributes.
If you pick Window or Crossing, only text entities are edited; but in
reverse order!

It edits one line at a time, but takes less RAM than PDSED and, since it's a
TSR program instead of a .SYS driver, it can be unloaded.  QEMM can load it
high (in the UMB above 640K).

It returns Errorlevel FFh if already installed, and FEh for DOS below 3.0.

KEYS:
ALT-E or ALT-R	pops up (but use TEXTED.LSP or ATEDIT.LSP instead)
INS		toggle insert/overtype
CTRL-BKSP	clears the line
HOME, END, DEL, Right & Left Arrows work as usual.
ENTER		goes back to the drawing & changes the text line

AutoCAD sends code 147d when ALT-R is hit.
It will not pop up at the DOS prompt.
AutoCAD does not disable TSR's, but this way AutoCAD can pop it
up from a .LSP routine.  It locates the text to edit by searching the screen
with INT 10h for the character AutoCAD displays as 174d.

You can change some defaults with a byte editor (like FileMod or
Norton Utilities).  Look through the .COM file for INS/OVERTYPE:.
The next byte is 01 for Insert, 00 for Overtype mode.
Following 'ATTRIB FOR EDIT WINDOW:', you can change the 17h (white on blue).
