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
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

Here are my 2 versions of "BOUNCE" and "BOUNCE" with PLOT. My versions include bytes saving.
OR 227 bytes in 16 lines
AB 150 bytes in 11 lines
OR 217 bytes in 14 lines (PLOT)
AB 176 bytes in 13 lines (PLOT)
All these versions do not run in 1K, but my version with 150 bytes does run in 2K.

I know I made a mistake: I uploaded this reply in the wrong topic. Now it is at its right place.
Have fun!
