>Does anyone have any VFP code to perform a checksum32? (CRC32)

I used an example in "C Programming Guide to Serial Communications" to create a CRC16. It had examples on how to do 8 bit, 16 bit, and 32 bit. It was pretty easy to code, but I had to use bitwise routines in FoxPro 5.0 or higher.

Remember to create an array of the fisrt 128 ASCII chars to speed up processing.
