Return the CRC32 of a given string.
Syntax:
nCrc32(nCRC32,cBuffer,[nLen],[[@]nStart]) -> nCRC32
Parameters:
<nCRC32>
Previous CRC32, use 0 to start a new string.Provide this parameter by reference to retrieve the new CRC32.
<cBuffer>
String to calculate the CRC32.
<nLen>
Number of characters to process. By default the length of the string.
<nStart>
1 based position of the first character to process. Default 1. You can provide this parameter by reference to get the next position after the calculation.
