91v

91v is an esoteric programming language created by User:Zero player rodent. It only has 9 memory cells that can be accessed. It has a large amount of commands, but the language is much less powerful than some other, more minimalistic languages, mostly because of the memory limitations. Although there are only 9 memory cells to be used, each cell can store infinitely large numbers.

Commands

Command	Outcome
1	Pointer jumps to cell 1, and adds 1 to pointer's memory.
2	Pointer jumps to cell 2, and adds 2 to pointer's memory.
3	Pointer jumps to cell 3, and adds 3 to pointer's memory.
4	Pointer jumps to cell 4, and adds 4 to pointer's memory.
5	Pointer jumps to cell 5, and adds 5 to pointer's memory.
6	Pointer jumps to cell 6, and adds 6 to pointer's memory.
7	Pointer jumps to cell 7, and adds 7 to pointer's memory.
8	Pointer jumps to cell 8, and adds 8 to pointer's memory.
9	Pointer jumps to cell 9, and adds 9 to pointer's memory.
?	Pointer jumps to a random cell.
v	Adds the number stored in the pointer's memory to cell the pointer is on.
"	Prints the ASCII character associated with the number on the cell the pointer is on.
p	Prints the pointer's memory as a number.
o	Prints the value of the cell that the pointer is on.
{	Sets the value of the cell that the pointer is on to 0.
}	Sets the pointer's memory to 0.
$	Gets a character from the input and stores it as an ASCII value in the cell the pointer is on.
;	Goes past the next ":" if the value of the cell the pointer is on is equal to 0.
:	Goes to last ";" if the value of the cell the pointer is on is higher than 0.
