Between

Between is an esoteric programming language created by User:Saka.
Between has functions which are positioned between arguments, hence the name.

Basics

Between is not stack based nor tape based. It is normal.
An instruction in Between is of the form

<arg1><operation><arg2>

For operations that accept only one argument, the arg2 must be a "None" type (See Data Types)

Data Types

Between has 5 data types:

Representation	Name
'x'	String
|x|	Integer
[x]	Variable
(x)	Condition (True or False)
.	None

Operations

Each operation is a single character and must be on it's own line. Comment lines start with #.

Operation	Description	Arg 1	Arg 2	Returns
p	Print arg1	String, Int, or Var	None	None
v	Declare variable with name arg1	String	None	None
s	Set variable arg1 to arg2	Var	String, Int, or Var	None
c	Toggle string/integer form of arg1 (Arg1 must only consist of numerals)	String, Int, or Var	None	String or Int
+	Add arg1 to arg2 (Or concatenate strings)	String, Int or Var	String, Int or Var	String or Int
*	Multiply arg1 by arg2	Int or Var	Int or Var	Int
=	Check if arg1 equals arg2	String, Int, or Var	String, Int, or Var	Condition
>	Check if arg1 is greater than arg2	Int or Var	Int or Va	Condition
r	Check if arg1 or arg2	Condition	Condition	Condition
n	Negate arg1	Condition	None	Condition
f	Go to arg1 if arg2 is true	Int or Var	Condition or None (If none, acts as a Goto)	None
i	Set arg1 to user string input	Var	None	None
x	Exit program	None	None	None
