Replace blocks in drawing with block from file with same name

Where "Y" is to replace existing blocks with the nameTOBY with the drawing called TOBY, so far nothing I have done is doing it. It just inserts a block like the one in the drawing.
....
To reach outside for a redefinition of a Block to an external drawing, use the Blockname=Drawingname format:
(command "_insert" "TOBY=C:\CAD\lib\Baseplan Symbols\TOBY" "Y" nil)
By the time it has been told to go ahead and update the definition, that has been replaced, and there is no need to complete the Insertion and then Erase it -- the nil cancels the command. Besides, finishing the Insertion and then Erasing the Last object will Erase something else [the last thing visible] if that Insertion at 0,0 is not at least partially visible in the current view.
If that drawing is in a Support File Search Path location, you don't need to give it the path, or even the name again:
(command "_insert" "TOBY=" "Y" nil)

Ok it doesnt respond to (command "_insert" "TOBY=C:\CAD\lib\Baseplan Symbols\TOBY" "Y" nil) ; error: Function cancelled

I should have noticed that before.... Because of the use of a backslash as a control character in text strings in AutoLisp, try using either a double backslash for a filepath separator:
(command "_insert" "TOBY=C:\\CAD\\lib\\Baseplan Symbols\\TOBY" "Y" nil)
or a single forward slash:
(command "_insert" "TOBY=C:/CAD/lib/Baseplan Symbols/TOBY" "Y" nil)
You'll see countless examples of this in code on these Forums. If I had modified @marko_ribar's suggestion [which uses the double backslashes] in Post 2 instead of your original, it would have been okay.
