SET DOT, CLR DOT, ; DOT(), TXPOINT and ; TXPOINT() doesn't work in ABC81

[mobluse]

When you run this below you get Error 200 in line 20. and similar when you use GOTO 30, GOTO 40, GOTO 50 etc. In ABC802 in ABCWin 2 they work. I know there are no working CUR() and TAB() now, but they don't give errors, and I don't think they should, but I think they should work eventually, and the semigraphics could also work if one use e.g. the font Bedstead.

10 NO EXTEND
20 SET DOT 33,42
30 CLR DOT 33,42
40 ; DOT(33,42)
50 TXPOINT 33,42
60 TXPOINT 33,42,0
70 ; TXPOINT(33,42)
