In this macro the CASMO5W assembler ignores the parameter count on the MACRO directive line The parameter count merely indicates the role of the parameter value passed to the macro That value is substituted for the sequential indicator 1 The first time this macro is called the CASMOS5W assembler changes the label loop on lines 3 and 4 to Joop 0001 If the calling line delay 100t invokes this macro the loop would occur 100 times The suffix t represents the decimal base The CASMOS5W assembler ignores extra parameter values sent to a macro If the macro does not receive enough parameter values the assembler issues an error message Labels change automatically each time they are used Labels used within macros may not be longer than 10 characters because the assembler appends a four digit hexadecimal number to the label to insure label uniqueness Although code may not jump into a macro it may jump out of a macro Macros cannot be forward referenced 5 12 M68ICSO5BOM D AA MOTOROLA ASSEMBLER INTERFACE 5 7 LISTING DIRECTIVES List directives are source code keywords that control output to the LST listing file These directives pertain only to viewing the source code output the directives which may be interspersed anywhere in source code do not affect the actual code assembled Table 5 4 summarizes the listing directives Table 5 3 Listing Directives Directive Action eject or page Begins a new pa
