Terry, the INTERNET_FLAG_PASSIVE is used in the InternetConnect function in wininet.dll.

The value is:
#define INTERNET_FLAG_PASSIVE 134217728

The usage is:
InternetConnect(THIS.nInet_Handle, (THIS.cIPAddress), VAL(THIS.cPort), THIS.cUserName), (THIS.cPassword), INTERNET_SERVICE_FTP, INTERNET_FLAG_PASSIVE, 0)

If your interested in this code bit, you can see all of it if you download the FTP_Class from the files section under Internet.
