Can anyone tell me what the error is in this line:

13 DISPLAY ERASE ALL :: CALL SCREEN(4):: @=0 :: FOR [email protected] TO 14 :: CALL COLOR(_,13,1):: NEXT _ :: CALL LOAD(-31878,0):: CALL LINK("NWCHAR"):: CALL TITLE

It returns a syntax error.
Would much appreciate it! :-)

I don't see one, unless you did not load the NWCHAR assembly language program via a CALL INIT and a CALL LOAD("") (xxx is the filename).

If you don't do a CALL INIT, any CALL LOAD or LINK will return a syntax error.
"DISPLAY ERASE ALL" looks right, but I wonder why not use CALL CLEAR here?

It is Extended BASIC, but it calls an assembly routine (the CALL LINK).
My question was whether the person loaded the assembly routine first. Usually you would see a CALL INIT followed by a CALL LOAD("device.filename") in the program, or you would execute it in command mode before running the program.
