IF NOT LEN INKEY$ THEN NEXT I

*Dr Beep :*

**12 IF NOT LEN INKEY$ THEN NEXT I**

Or

Just one line to wait:

11 RAND SIN SIN SIN SIN SIN SIN PI

Code: Select all

```
1 LET X=42
2 LET Y=X
3 LET X1=PI/PI
4 LET Y1=X1
5 FOR I=X1 TO PI STEP 0
6 LET X=X+X1
7 LET Y=Y+Y1
8 IF X<1 OR X>42 THEN LET X1=-X1
9 IF Y<1 OR Y>62 THEN LET Y1=-Y1
10 PLOT Y,X
11 RAND SIN SIN PI
12 UNPLOT Y,X
13 IF INKEY$="" THEN NEXT I
14 REM DONKEYSOFT
```
