>>>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.

To be fair, I didn't understand what you want to do exactly.
What format do you have to convert in what format. When you say "binary number", is it a number in numeric format or a number in string format? The same for HEX: is it numeric HEX or string HEX?

If both of them are numeric, than there may be nothing to convert. Altough, if you need to write them to a file you may need some conversions.

Please tell us exactly what you need to do. What's the input, what's the output?

You say that the binary format may be: 1100001111010001. Does it mean "1100001111010001"? Do you have actually 16 bytes there?

For example, the HEX equivalent in string format is "C3D1", but the memory value in string format is chr(195)+chr(209).
