Good Morning,

 

Jonny Mac recently posted a neat series of routines that printed out bin hex and Dec results from Byte parameters.  I thought that was really cool but needed a Decimal printout of a Word Varable.  So I edited his routine and came up with the following:

 

' -------------------------------------------------------------------------

' Use: TX_DEC5 value
' -- transmit word in (fixed-width) DEC5 format

'--------------------------------------------------------------------------

SUB TX_DEC5
 dvalW  VAR TmpW1

 divisorW VAR tmpW2

 dDigit  Var tmpB1

 dChar  Var tmpB2

 

  dValW = __wPARAM12                        ' copy output value
  divisorW = 10000                               ' set initial divisor

  FOR dDigit = 4 TO 0 STEP -1                ' show three digits
    __wparam34 = dValW / divisorW           ' get a digit
    dValW = __wREMAINDER                     ' save remainder
   dChar = __param3                             ' it going to be <10 
   dChar = dChar + "0"                           ' convert to ASCII
    TX_BYTE dChar 
    divisorW = divisorW / 10                     ' update divisor
  NEXT
  
ENDSUB


if I declare tmpW1 = 23456  or any 5 digit number short of 65,535:

   TX_DEC5 tmpW1

 

my results always come out 00000.

I wonder if I have one temp varable stepping on another.  When I look at .lst file I do find some VAR with the same address.  I am I missing something?  It is hard to step through the Devide by 10,000 to see what is happening.  I tried setting dChar = dValw / divisorW but it is expecting a word param not a byte and wont compile.
