Actually I was with the assumption that each line should not have colons for joining.

Like this:

Code:

1 IF I% = 0 THEN SCREEN 7, , 0, 1 ELSE PCOPY 0, 1
2 A! = (A! + .03) * -(A! < 6.283186)
3 FOR I% = 0 TO 200
4 x! = ((50 * COS(4 * 3.141593 / 200 * I%)) * (COS(A!) * COS(A!)) + (50 * SIN(8 * 3.141593 / 200 * I%)) * (SIN(A!) * SIN(A!) * COS(A!) - COS(A!) * SIN(A!)) + (I% - (200 / 2)) * (COS(A!) * SIN(A!) * COS(A!) + SIN(A!) * SIN(A!)))

7 IF I% > 1 THEN CIRCLE ((160 + (256 * x! \ (256 - z!))), (100 - (256 * y! \ (256 - z!)))), 512 \ (256 - z!), (A! * 57.29577 + I%) AND 15 ELSE LINE (0, 0)-(319, 199), 0, BF
8 NEXT I%
9 IF INKEY$ = "" THEN 1

Code:

6 PSET (32 + xa%, 36 + ya%), (xa% + xsin%) XOR (ya% + (Lsin%((xa%), 0)))

Note that I had to strain my brain just to get it to work fast enough and there is no colon joined line. ;*)
