This procedure was written to check for the existence of a table on either the IFS or a network server. Using the c function Access for the IFS and for the network FTPing to the server and attempting a rename to itself. Then checking the FTP output file for error. This is just for an example. Feel free to download the code and make changes as required. Our hope is that you will come back and use the BLOG response process to re-post you example.
