Create Zip in a BinData Object

Recursively appends files in a directory tree and writes a zip archive into a Chilkat BinData object. PowerBuilder

// not read the file contents or append them to the zip

// into the .zip output file (or BinData object).

// Or the zip can be used by some other Chilkat method call that accepts
