> | III.1 Statements Source files consist of a sequence of statements of one of the forms:
>     [symbol:]  [instruction [arguments]]     [;comment]

>      symbol     instruction  argument        [;comment]

>     $control   [(argument)]                  [;comment]
Everything that is written in brackets is optional. The maximum length of source code lines is 255 characters. Everything from the ';' character to the end of line is assumed to be commentary. Blank lines are considered to be commentary, too. The lexical elements of a statement may be separated by blanks and tabs. Aside of character string constants, upper and lower case letters are equivalent. Examples:
        HERE:   MOV A,#0FFH     ;define label HERE and load A with FFH

                YEAR EQU 2002   ;define symbol for current year
