Hullo,

Try the following links (the documents are based on old SAP R/3 versions (iirc 4.0) but the principles explained in these documetns are still very valid today).

<a href="http://www.allsaplinks.com/files/intro_to_dialog_prg.pdf">An introduction to dialog programming</a>

Plus the files section of this site (allsaplinks) contains more material on Dialog programming (= module pool programming):

http://www.allsaplinks.com/dialog_programming.html

Hope this Helps.
