[Example] If you want to define the name and phone number as character string data 
   

  These data definitions are expanded as follows. 

  tel TANAKA, 12-3456
 +  +00000000 54414E41 dc / TANAKA /
 +  +00000004 4B41
 +  +00000006 31322D33 dc / 12-3456 /
 +  + 0000000A 343536
  tel KOJIMA, 98-7788
 +  + 0000000D 4B4F4A49 dc / KOJIMA /
 +  +00000011 4D41
 +  +00000013 39382D37 dc / 98-7788 /
  +00000017 373838 

.  By using macro definitions in this way, MPU (micro processing unit) is essentially used.
 Advanced programming is possible rather than directly using the instructions in .
  Here is the data definition of the phone number used here as an example. 

 Uses instruction direct macro of 68K 
  dc / TANAKA / tel TANAKA, 12-3456
  dc / 12-3456 / tel KOJIMA, 98-7788
  dc / KOJIMA /
  dc / 98-7788 / 

:  In this way, using a macro makes the description simpler and easier to understand. 

EXITM

  format  EXITM 

 Description  The EXITM pseudo-instruction is used to forcibly terminate MACRO, REPT, IRP, and IRPC.
When   EXITM is executed, macro expansion is immediately stopped and the next line moves.
