Track is a two-dimensional esoteric programming language made by User:Wh1teWolf. It has a two-dimensional instruction area of 30x? instruction cells, and a one-dimensional memory array,

Commands:

  • > : "walking" direction is right
  • < : "walking" direction is left
  • ^ : "walking" direction is up
  • V : "walking" direction is down
  • @ : "walking" direction is decided by the number under pointer. 1=right, 2=left, 3=down, 4=up (All other numbers==right)
  • + : Add one to cell under pointer
  • - : Subtract one from cell under pointer
  • . : Output ascii character under pointer
  •  : : Output number under pointer
  • , : Input ascii character in cell under pointer
  •  ; : Input number under in cell pointer
  • 0-9: Move memory pointer to cell n

Examples:

Infinite loop:

V<
>^

This program shows how the "walking" direction stuff works. The first instruction is "V", making the program move down to the next line where there is a ">" instruction, this changes the "walking" direction to right. We go right one step where there is a "^" and are pointed up to the "<" instruction, this makes us go left to the starting point and so on...

Counting from 1 to 10:

V               V       <     
>1++++++++++++++>1-0+:1@^     

This example could also be written like this (which is the best way of doing it):

++++++++++++++>0-1+:0@V       
              ^       <
