Jeffrey, I just happened to snag that one into my "tips" folder. Here's a repost: hth, Eric DeLong -----Original Message----- From: Jeffrey Silberberg [mailto:jsilberberg@mindspring.com] Sent: Thursday, April 26, 2001 10:37 AM To: midrange-l@midrange.com Subject: Seen It, But can"t find it now. Morning, Had someone ask me this morning for sample ILE/RPG code to do a Post/Get to a remote Web site for the purpose of exchanging data. I know I have seen a sample piece of code somewhere to do this I just can not seem to locate it today. Does anyone else happen to have a bookmark to this information ? Thks, Jeffrey M.
