Still stuck.... sorry, I must be missing something...

[code]MenuMain:
  DATA 11,"asdfklke ka", 0
  DATA  8,"mike8cha", 0


The menu has been changed to protect the innocent! :)  However, this is not behaving as expected... the only difference between this code and the original LCD_STR code is the lack of supporting the Z flag...  but when I add

 

        menumain = menumain + Z it fails because menumain is a string pointer I believe.... so is that what is failing here?  If so... I would like to just extend LCD_STR to include a third parameter (index) that would handle this... but I had problems doing that as well...

 

For reference here is the LCD_OUT and LCD_STR as they exist today... 

 



[code]
' -------------------------------------------------------------------------
' Use: LCD_OUT theByte {, count }
' -- sends "theByte" to LCD [optional] "count" times
' -- "count" defaults to 1 if not specified
LCD_OUT:
  temp1 = __PARAM1    ' save the byte
  IF __PARAMCNT = 2 THEN   ' "count" specified?
    temp2 = __PARAM2    ' yes, save
  ELSE
    temp2 = 1     ' no, set to 1
  ENDIF
  DO WHILE temp2 > 0
    SEROUT LcdTx, LcdBaud, temp1  ' transmit to LCD
    DEC temp2
  LOOP
  RETURN 


' -------------------------------------------------------------------------
' Use: LCD_STR [ string | label ]
' -- "string" is an embedded literal string
' -- "label" is DATA statement label for stored z-String
LCD_STR:
  temp3 = __PARAM1                              ' get string offset
  temp4 = __PARAM2                              ' get string base
  DO
    READ temp4 + temp3, temp5                   ' read a character
    IF temp5 = 0 THEN EXIT                      ' if 0, string complete
    LCD_OUT temp5                      ' send the byte
    INC temp3                                   ' point to next character
    temp4 = temp4 + Z                           ' update base on overflow
  LOOP
  RETURN
