PointerTape

PointerTape is a tape-based programming language created by User:Asymptote. It is, as yet, incomplete.

PointerTape is quite simple. A PT program consists of a "tape" (array) of symbols.

Symbol	Function
>	Moves the pointer to the right.
<	Moves the pointer to the left.
H	Halts the program.
wxy	Writes the symbol x (either < or >) in the direction of y (also either < or >).
wxn	Writes the symbol x (< or >) at position n.
jn	Makes the pointer jump to position n.

As noted above, there is a great deal of functionality yet to be implemented in PT. A list of possible upcoming symbols follows:

Symbol	Function
x	Stores the object x (which can be any Python-compatible variable)
sxp	Creates a storage symbol at position p, and stores the value x there.
px	Prints the symbol in the direction x (x is < or >).
pn	prints the sybmol at position n.
E	Causes the program to exit.

As soon as the needed functionality is implemented, the standard "Hello, world!" application will be posted. It should be something like this:

[p13,p14,p15,p16,p17,p18,p19,p20,p21,p22,p23,p24,p25,"H","e","l","l","o",","," ","w","o","r","l","d","!"]
