RosAsm Specifics  ..

        

        

Multi instructions lines

        

mov eax ebx | mov ecx 0 | call My_Routine    ;   ' | ' and 'CR/LF' are equivalent

Multi lines instructions

        

          My_Macro_Evocation,       ; this is a macro evocation with 3 parameters:

                    AAA1,                        ; First one

                      BBB2,                       ; Second one

                        CCC3                     ; Third one

                        

                                                     ; commas mean 'not over...'

All source text that is not purely encodable instructions is inside square  brackets: Data, Equates and Macros

          

Data:      [First_value: 36  List_of_values: 44 126 32]

          

Equates:  [true 1  false 0]

          

Macro:    [Simple_Storage | mov al B§esi | mov ah B§esi+1]

          

RosAsm looks at the first separator sign following the first name inside square brackets:

          

Space >>>   equates

Colon >>>   data

Pipe or CR/LF >>>   macro

        

For Addressing syntax, see Data_Access.

Basically, any symbol (like with NASM) is an Address, and nothing else. To access a Value at a given symbolic Address, you have to provide the Size marker (D$Symbol / W$Symbol / B$Symbol). This makes the overall syntax clean, clear and univoque.

Comments

Like in most Assemblers, Comments begin  with a Semi-Colon and go up to the end of line:

; This is a Comment.

You can also have Multi-Line Comments with Double-Semi-Colons, alone one a line, at first  row:

;;

This is

     a Multi-Lines

            Comment.

;;

Internally (for the Editor and for the Assembler, the MLC (Multi-Line Comment) Marker is in fact 'LF ; ; CR'. That implies that the Double-Semi-Colons have to come alone on a single Line, First row, CR/LF ended. Anyway, the Editor colors will save you from any  typing errors with this.

As opposed to Square Brackets and Strings Quotes, the Double-Semi-Colons do not require to be paired. For example, you may end your Source with a 'To-Do' List, just beginning by an open (never closed) Double-Semi-Colons.
