I purchased and read "Understanding the IBM WebFacing Tool" by Claus Weiss before attending a WebFacing seminar by Mr. Weiss at our Philadelphia PA computer users group.Mr. Weiss is very effective and impressive in both his presentation and in his book in leading legacy programmers, like me, into the world of GUI and the Web in easy and understandable steps.I learned much from from the book, particularly how RPG and COBOL legacy programs can be easily modernized, along with the legacy programmers who still prefer to write in those languages.A user group associate, Joe Mariani, borrowed my WebFacing book four months ago to guide him in actually implementing the WebFacing Tool at his company. Each month, Joe explains to me how he is still actively using the book and benefiting from the code and concepts illustrated in Claus's book.Paul H. Harkins
