!<COMPREHENSIVE CHECKER: OPCODES IN PASS 2>
   
!Purpose: 
!This program tests if the assembler can recognize 
!all instruction opcodes in pass 2.

!Description:
!All types of instruction opcodes are used in the .text section.
!Basic instruction formats, basic register names, 
!and, if necessary, the simplest expressions are used.
