Tokens

Here's the list of tokens that manipulate items on the stack. Nilads take no values from the stack, monads take one, and dyads take two.

The general rule for the character chosen for a function:

• Nilad/general maths; standard alphabetical character
• Monad taking int; uppercase bold
• Monad taking list; lowercase bold
• Dyads; double struck
• Loops, conditionals etc; uppercase greek
• Variables; lowercase greek.

Special Cases:

• For certain characters, the ) character is not required at the end if the end is the end of the file.

Additionally, if a token takes a list but instead an int is popped, the int will be exploded into a list and vice versa.

Token	Input	Function
₁		Get first input line
₂		Get second input line
₃		Get third input line
Γ .. )	any	Perform the operation(s) .. on each element in the list. Implicit exclusive range if integer.
Δ .. )	any	If integer, create inclusive range or if list, add one to each value. Then perform the operation(s) .. on each element.
Θ		Push currently looped value or 100 if not in loop
Λ .. )	list	Keep those in the list where <elem> .. is equal to 1
Ξ .. )	any	If int and equal to 1, or if list and contains 1, do ..
Π	any	Assign the next variable to the top value in the stack
Σ .. )	list	Keep those in the list where <elem> .. is equal to 0
Φ		Push index in loop or 256 if not in loop
Ψ	list	Apply the next token to each element in the list
& .. )		Create a list of the elements pushed in ..
$		Wrap stack to array
( .. )		Decompress a base 255 string
)		Close loop/conditional etc.
_	list	Push each element to the stack
>	int	Increment
<	int	Decrement
B	int	Compress a number into base 255
D	any	Duplicate
I		Take one line of input
Q		Terminate program
R		Randomly choose 1 or 0
U	any	Duplicate from underneath: a, b -> a, b, a
c		Infinite list of perfect numbers (0-indexed)
f		Infinite list of fibonacci numbers (well, up until 2^63-1)
