Calligulan Assembly

Calligulan Assembly is an esoteric programming language created by User:ArthroStar11 that is written entirely in Roman Numerals

Data Structure and Syntax

• Commands and arguments in Calligulan Assembly are represented as roman numerals separated by newlines
  • capital letters represent the numerals we all know and love
  • the values of lower case letters are multiplied by 1000
• data structure
  • hold cell (32-bit unsigned integer)
  • boolean cell (boolean value, duh)
  • variables [array of 30000, 1-index] (32-bit unsigned integer)

Command List

• I (Label)
  • defines a label for goto statements, 30000 labels may be used (I - xxx) as specified in <line + 1>
• II (go to)
  • jumps to the corresponding label as specified in <line + 1> if the boolean cell is true
• III (less than)
  • sets the boolean cell to true if <variable[line + 1]> is less than <variable[line + 2]> else false
• IV (equal to)
  • sets the boolean cell to true if <variable[line + 1]> is equal to <variable[line + 2]> else false
• V (not)
  • inverts the boolean cell
• VI (input)
  • takes console input as an ASCII character if <line + 1> == I
  • takes console input as a number if <line + 1> == II
  • stored in hold cell
• VII (output)
  • outputs an ASCII character to the console if <line + 1> == I
  • outputs a number to the console if <line + 1> == II
  • printed from hold cell
• VIII (store)
  • stores the value of the hold cell into the variable specified in <line + 1>
• IX (retrieve)
  • retrieves value of the variable specified in <line + 1> and stores it in the hold cell
• X (add)
  • hold cell = <variable[line + 1]> + <variable[line + 2]>
• XI (subtract)
  • hold cell = <variable[line + 1]> - <variable[line + 2]>
• XII (constant)
  • stores the number specified by <line + 1> into the hold cell
