Guenther and everyone...
I would in NO WAY be offended by programing tips.  I am very new to this, and any help is greatly appreciated!  I was about to reply to your first message Guenther that i had copied those couple lines from the compiled sx/b code, so ...  well anyways  :)  I see you have all cleared up the mistakes I was making.  I was not using a 16 bit index...  I had tried the 16 bit index but then i was copying it wrong.  Anyways here is what i came up with and it seems to work.



[code]
Main:   

  bank    COUNTS
  MOV     idx,#0  
  MOV     idx+1,#0
  mov     char,#LcdCls       ;clear the screen
  call    LCD_OUT   

Label_Message:
  mov     idx,  #tmsg & 255
  mov     idx+1,#tmsg >> 8
  
:DO 

  MOV M,idx+1                ;move top 4 bits of tmsg into the m register
  mov W,idx                  ;move bottom 8 bits into the W register
  IREAD                      ;reads the char and pos w+m into W
  mov  char, W               ;moves the char at w into char
  CJE char,#0,@scroll        ;done with the top line, do the bottom line now
  call @LCD_OUT
  ADD idx,#1
  snc
  inc idx+1
  JMP @:DO 
[/code]

Paul, 

I was thinking about using a jump table, but this is going to be using more than 300 characters (eventually, i will just use an eeprom).  And thanks for the pointers, they helped alot.

 

Bean,

Yea, you are right, duh on my part.  I think i was just getting frustrated.  (at least that's my story)  Thanks!

 

 

One more question, I can't find an answer to in the manuals...  Does the line: [MOV idx+1, #tmsg >> 8] do 8 rotate rights?  I am assuming that from the outcome, but I am not sure.  I have your book Guenther, (and its the BEST) but I can't seem to find where something like that would be explained.  I have looked at the MOV instruction and the >> but none seem to fit.

 

Thanks all you SX god-like people,
John Gjonola :)
