VFP provides the BITSET() function to set a bit in a numeric value directly.

There's no need to do all those conversions. Just work with numeric values.

>>Hi Craig,

>>I'd suggest a two step approach, the first being to convert the binary string to an integer, then covert the integer to hex. I recently saw a routine to do the latter conversion, so here's the first part:

>>FUNCTION BStr2Int

>>LPARAMETER pc_bstr
>>
>>LOCAL lnresult, lni, lnj, lnlast
>>lnlast = LEN(pc_bstr)
>>lnj = -1
>>lnresult = 0
>>FOR lni = lnlast TO 1 STEP -1
>> lnj = lnj + 1
>> lnresult = lnresult + (VAL(SUBSTR(pc_bstr, lni, 1)) * (2 ^ lnj))
>>NEXT
>>RETURN lnresult

>Thanks George, I'll try it out. What I'm needing to do is transmit data to a remote server program. The remote program can accept optional fields i the middle of the string. The first field to send is a hex representation of the binary on/off (yes/no) of which fields are sent. For example, if field 5 is sent, then the 5th position in the binary number is set, etc.
