  You can add 30 to the value to convert to ascii
  
  example:
  30 + 0 = 30 = ASCII '0'
  30 + 1 = 31 = ASCII '1'
  etc.

  Just to clarify Rodney's answer that would be hex 30 or decimal 48.

  Thanks Mike!
  
  BTW, I'm starting to give my age in hex as people don't seem to question the $ [noparse]:o[/noparse])

  Thanks Rodney,
  
  That would help a lot, only problem is I have a range of·decimals -2500 through 2500 that I need to convert to the·same number, only in string format instead of decimal.· I'm probable going to switch this project to·a BS2.· I'm more familliar with PBASIC that SX/B.· But if anyone knows how to do this in SX/B, please speak up.
  
  Thanks a lot.

  You'll need to write a subroutine to do that, In fact I thought someone posted one a while back that would do a 4 or 5 digit word value, you might want to dig through the SX forum.·Anyway here is one to do a 3 digit decimal number:
  
  

  ' -----------------------------------------------------------------------------
  ' Use: TX_DEC3 value aByte
  ' -- displays value in Decimal format (text), Does not supress leading Zero's
  ' --
  
  TX_DEC3:
    
    temp2 = __PARAM1                      ' copy output value
    temp2 = temp2 / 100                   ' get 100's digit
    temp3 = __REMAINDER                   ' save 10's & 1's
    temp1 = "0" + temp2                   ' make 100's character
    TX_BYTE temp1                         ' print it
    temp2 = temp3 / 10                    ' get 10's digit 
    temp3 = __REMAINDER                   ' save 1's
    temp1 = "0" + temp2                   ' make 10's character
    TX_BYTE temp1                         ' print it
    temp1 = "0" + temp3                   ' make 1's character
    TX_BYTE temp1                         ' print it
    RETURN                                ' return to caller

  Thanks Mike,
  As soon as I get my serial cable back from my dad, I'll try that. It doesn't look like it will be to difficult to modify for 4 digits. Thanks Again.

  http://www.sxlist.com/techref/ubicom/lib/math/radix/index_sx.htm ·has a page with many subroutines that can do that. Your value is going to need to be converted to a positive binary number first and then to an ASCII string. So if it is negative, print the "-" then make it positive (number = 0-number) and then in either case, call one of the subroutines for 12 binary bits or better (2^12=4096 > 2500 > 2^11=2048) to make an ASCII string.
  
  Probably the best fit is this one:
  
  http://www.sxlist.com/techref/ubicom/lib/math/radix/b2a-16b5a-rl_sx.htm which is 16 bits in and 5 digits out.

  Mike, just double checking, to call the TX_DEC3 subroutine, you would use something like
  
  TX_DEC3 150
  
  correct?

  The way I use this routine would be to pass the number via a variable:
  
  idx = 150
  
  TX_DEC3 idx
  
  
  
  Also to use the SUB you will need to define it, take a look at the attached file.
