Below is the beginning of a macro definition for a macro named QUIZ that uses two arguments. Almost any kind of argument is allowed for either FIRST or SECOND; thus, all of the following are valid:
QUIZ @(R10), XYZ-OFF+3 QUIZ OFF(R6)[R8], #22 QUIZ R7, -17(R9)However, it is illegal for SECOND to be in autoincrement form, such as (R8)+ or (R10)+ or @(R7)+ Write statements inside QUIZ that check for all such illegal arguments; if an autoincrement argument is found, report an error message and terminate the macro expansion.
