Coding rules

• File and function names must start with a lower case letter.

• Routines' structure is this way :

  :myRoutine
      SET B, 1
      SET B, 2
      :myRoutine_subroutine
          ADD B, 1
          MUl B, 5
          :myRoutine_subroutine_loop
              ADD B, 1
              IFN B, 100
              SET PC, myRoutine_subroutine_loop
      SET PC, POP
  

• It is strongly suggested to comment the routine explaining how it works and what are its arguments / return values. (Ex: ;A : Pointer to a null-terminated string)

• Instructions (set, add, mul, div, etc) must be in lower case.

• Registers (A, B, C, I, J, X, Y, Z) must be written in upper case.

• PUSH, POP and PEEK also must be written in upper case.

• There is a space after the comma, but not before.

• Operators + and - must be surrounded by spaces. Ex: SET [I + screen_address], C

• define names must be in upper case. Ex: #define MY_DEFINE 42

• Cold must be indented once for every step in the hierarchy of routines. The tab must be the character "\t" and not 4 spaces.

Correct code example

:myRoutine
    set PUSH, A
    set A, 0
    :myRoutine_loop
        add A, 1
        ifn A, 100
            set PC, myRoutine
    jsr anotherRoutine
    set [I + screen_address], C
    set PC, POP
