Title : VAX_BASIC_TCPWARE_FTP_SAMPLE.BAS" ! Author : Neil S. Rieck (Waterloo, Ontario, Canada) ! : (https://neilrieck.net) (mailto:n.rieck@bell.net) ! Purpose: to explore the possibility of controlling an FTP transfer from within VAX-BASIC applications ! Notes : 1. written in VAX BASIC 3.8 running under OpenVMS 6.2 using Process Software's TCPware 5.3 ! 2. derived from file "ftp_sample.c" in TCPware's example directory which is ! copyrighted (c) by Process Software Corporation of Framingham, Massachusetts, USA. ! 3. by declaring passing mechanisms in the "external" declarations we won't need to use VAX-BASIC's ! "LOC" function statement to substitute for DEC-Cs ampersand (address reference) ! 4. optionally, rename this file to "ftp_sample.bas" ! 5. build the executable as follows: ! $ basic ftp_sample.bas ! $ link ftp_sample, sys$input/options ! sys$share:tcpware_ftplib_shr/share ! sys$share:tcpware_socklib_shr/share ! 6. interface to dcl as a foreign command like so: ! $ftp_sample :== $ sys$help:ftp_sample.exe !========================================================================================================================= !
