I’m making Snake in Axe as practice, but my code isn’t working and I can’t figure out what’s wrong. The Snake is supposed to be longer, but I can only make it be one segment. What did I do wrong? Here’s my code. Thanks in advance!

:.SNAKE
:DiagnosticOff
:ClrHome
:
:.sprites
:[E0A0E00000000000]->Pic0BODY
:[1F1F1FFFFFFFFFFF]->Pic0FILL
:
:.v\ariable RAM
:|E9872->->^^oVR
:
:.create v\ars
:^^oVR->->^^oHeadX+2->->^^oHeadY+2->->^^oDir+2->->^^oTail+2->->^^oLength
:
:.set v\ars
:0->HeadX->HeadY
:1->Tail+6->Length
:3->Dir
:
:.set list
:Data(0,0,0,0,0,0)->GDB1SEGX
:Data(0,0,0,0,0,0)->GDB1SEGY
:
:.game loop
:Repeat getKey(15)
:   
:   .erase tail
:   Pt-And({Tail-1+GDB1SEGX},{Tail-1+GDB1SEGY},Pic0FILL)
:   
:   .draw head
:   Pt-On(HeadX,HeadY,Pic0BODY)
:   
:   .update list
:   HeadX->{Tail-1+GDB1SEGX}
:   HeadY->{Tail-1+GDB1SEGY}
:   
:   .get input
:   getKey->Ans
:   If Ans?Ans<=4
:      
:      Ans->Dir
:      
:   End
:   
:   .move
:   (Dir=3)-(Dir=2)+HeadX->HeadX
:   (Dir=1)-(Dir=4)+HeadY->HeadY
:   
:   .update tail
:   Tail+1-(Length*(Tail=Length))->Tail
:   
:   .draw screen
:   DispGraphClrDraw
:   
:End

Side note: what is the bbcode for a code box? I clicked the bbcode button on SourceCoder, but that makes it a quote with a bunch of styling. How do I make the code box that you can click "copy" on?

Never mind, I found out what was wrong with snake. I forgot DispGraphClrDraw cleared the current buffer.
