Interprogck8

Interprogck8 is an esolang by User:PythonshellDebugwindow. It uses a mixture of normal integers and "dice literals" to store values in its single accumulator.

Memory

Interprogck8 uses a single accumulator, also called the value cell, which has a wraparound integer value from 0 to 255 starting at 0, and Interprogck8 also has a single function called the current function.

Syntax

Interprogck8 programs are made of a series of commands, one per line. Empty lines count as commands, and since there is no 0-length instruction, blank lines will raise errors.

Dice literals

Dice literals are a unique way Interprogck8 stores values. They are so named because they are intended to resemble the faces on a die. For example, one would be represented as "." (minus the quotes), two as ":", three as ":.", and so on.

Commands

Bolded characters represent wildcards, explained in more detail in the Meaning and Notes columns.

Instruction	Meaning	Notes
z	Delete the previous line/instruction and restarts the interpretation. Also deletes this "z" to prevent errors and/or infinite reinterpretation loops.	Raises "FirstLineError" if it's on the first line.
[a b]	Generates and sets the accumulator to a random number between a and b inclusive, where they're both dice literals (see above section).	If you leave a and/or b empty, they will assume the value of the value cell. If you put a "$py" (see later in this section) as a and/or b, the accumulator won't be changed by those commands and instead their result will be passed to whichever parameter they occupied.
{values/=a/=b/=c}	Checks if a, b, and c are different; sets the accumulator to 84 (ASCII "T") if at least 2 are different and 81 (ASCII "Q") otherwise.	If you leave a, b, and/or c empty, the empty one(s) will assume the value of the value cell. If you put a "[a b]", a "$py" (see later in this section), or a "u" (see later in this section) as a, b, and/or c, the accumulator won't be changed by those commands and instead their result will be passed to whichever parameter they occupied.
IFT	If the accumulator is equal to 84 (ASCII "T"), executes the current function.	For use with "{values/=a/=b/=c}". The current function is kept.
IFQ	If the accumulator is equal to 81 (ASCII "Q"), executes the current function.	For use with "{values/=a/=b/=c}". The current function is kept.
<	Opens the current function.	Functions can't be created inside other functions. Functions use and change the same accumulator used by the rest of the program, including other functions.
>	Closes the current function.	See "<".
EXE	Executes the current function.	The current function is kept.
@nd	Adds 1 to the accumulator.	Meant to resemble the word "and".
@nt	Subtracts 1 from the accumulator.	Meant to resemble the word "ant".
@id	Adds 10 to the accumulator.	Meant to resemble the word "aid".
@dd	Subtracts 10 from the accumulator.	Meant to resemble the word "add".
$py	Sets the accumulator to user input (must be a dice literal (see above section), if not gives an error).	Meant to resemble the word "spy".
$ay	Outputs the value of the accumulator as a dice literal (see above section).	Meant to resemble the word "say".
mathroundtofloor	Sets the accumulator to the floored value of the accumulator plus 0.5.	Essentially a nop command, as the accumulator is always an integer with no decimal point.
developer	Prints the interpreter's source code.	Technically implementation-dependent.
u	Sets the accumulator to the ASCII character of the first character of user input.	Raises "EmptyInputError" if input is empty.
X	Nop.
x	Nop.
~	Nop with a 10% percent to print "Interprogck8" and then a newline.
NnNn	Sets the accumulator to 0.
nNnN	Sets the accumulator to 65.	Useful for output.
Empty_	Sets the accumulator to 32.	Useful for output.
DownAccLines	Makes the instruction pointer skip down accumulator lines.	Raises "EOFError" if there aren't enough lines to skip down.
Instruction26	Prints the numbers 1 to 26 separated by the ASCII character of the value cell.
div	Prints out the ASCII character of the value cell.
