I Need Assistance in Salvaging a Particle for current GF....

[JayPro]

This gem called Byte Snakes from Ted worked just fine with my GF 3.0.1; but now it's doing nothing but scribbling lines.
I checked exhaustively for syntax, which I knew had to be right coz it worked as I said before.
I even streamlined the deprecated funcs to see if that would help. No go on that as well.

Anyway, this is supposed to draw randomized squares and the formula reads thus:

Stps="rnd(34) + 6",
Aspc=0,
A0="rnd( 1 )", // seed function randomizer
A1=".02 + rnd ( .06 )", // box width
A2="t",
A3="rnd( 3 ) + 1", // speed
B0="flor( ( t - a2 ) * a3 )",
B1="1 - sqwv( 3 * ( b0 - b2 ) )", // movement timer
B2="b0", // last frame memory
B3="b3 + b1", // counter
B4="b3 % 2", // axis shifter
B5="seed( b3 + a0 )",
B6="sgn( rnd( 2 ) - 1 ) * a1 * b1", // movement tensor
B7="b7 + b6 * b4", // iterative X
B8="b8 + b6 * ( 1 - b4 )", // iterative Y
C0="flor( s * ( NUM_S_STEPS - 1 ) )", // convert steps to integers
C1="( b3 + c0 ) % 2", // axis shifter
C2="seed( b3 + c0 + a0 )",
C3="sgn( rnd( 2 ) - 1 ) * a1", // movement factor
C4="( c4 + c3 * c1 )* clip( c0 )", // iterative X
C5="( c5 + c3 * ( 1 - c1 ) ) * clip( c0 )", // iterative Y
C6="1.8 * trwv(b7+c4 + .45) - .9",
C7="1.8 * trwv(b8+c5 + .45) - .9",
X0=" c6",
Y0=" c7",
X1="-c6",
Y1=" c7",
X2=" c6",
Y2="-c7",
X3="-c6",
Y3="-c7",
Pen=".5 + .5 * s",
ConB=1,
LWdt="2"
Meta="reactive=1, detail=3, density=3",
Vers=270

It would seem to me that there ought to be something missing/outdated rather than flat-out wrong.
I'd deeply appreciate any first responders here, as I'm almost through with my sizeable data shift to the current GF...and this hold-up's driving me batty. Thank You.
