Appendix B: Suggest Labels

RUN  - code to run
LOOP - create a loop
MLOOP - create a main loop



A     Add (words)

  Example:
  
  A R3,R4

  This examples takes value in the first register (R3), add the second 
  Register (R4), and stores new  number into the second register (R4).



AI    Add immediately 

  Add numbers not yet stored.



AB    Add Bytes



C     Compare words



CB    Compare Bytes



MOV   MOVe word

  Example 1:

  MOV *R5,R0
  
  Example 2:
  
  MOV  *R1+,R0



MOVB  MOVe Byte



S     Substract (words)



SB    Subtract Bytes



SOC   Set Ones Corresponding


SOCB  Set Ones Corresponding, Byte


SZC   Set Zeros Corresponding



SZCB  Set Zeros Corresponding, Byte



JEQ   Jump if EQual 



JGT   Jump if Greater Than 



JH    Jump if logical High 



JHE   Jump If High or Equal 



JL    Jump if logical Low 



JLE   Jump if Low or Equal 


JLT   Jump if Less Than 



JMP   unconditional JuMP 

  Example:

  JMP   LOOP  ; jump to a label



JNC   Jump if No Cairy 


JNE   Jump if Not Equal 


JNO   Jump if No Overflow 


JOC   Jump On Carry 



JOP   Jump if Odd Parity



CI    Compare Immediate



LI    Load Immediate

  Example: 
  
  LI R0,367   ; 367 = video display
  LI R1,88    ; character 88 (x) into register 1



SWPB  swap byte

  Example: 
  
         DEF  RUN
         REF  VSBW
  RUN
         LI   R0,367
         LI   R1,88  
         SWPB 1      ; swap bytes so 88 comes first
         BLWP @VSBW
  LOOP   JMP  LOOP
         END



BLWP



DATA  Store data

  Example:
  
  DATA >008B



TEXT  Store Text


  Example 1:


      TEXT 'THIS IS TEXT'
  
  Example 2:
  
         DEF  GREET
         REF  VMBW
 
  MSG1   DATA >008B
         DATA >0008
         TEXT 'WELCOME!'
 
  GREET
         LI   R1,MSG1
         MOV  *R1+,R0
         MOV  *R1+,R2
         BLWP @VMBW
  FREEZ  JMP  FREEZ
         END
