Abstract

A programming technique is disclosed which can be used to prevent looping problems in products that provide access to host systems, specifically those which provide the capability to recognize host screens and automatically navigate to subsequent screens. This invention solves the two types of looping problems that can be found in these type of products: 1) Automatic screen navigation path loop When a particular host screen is recognized, it can be automatically bypassed by having some predefined command or key entered. If the next screen presented by the host is also recognized, it too can be automatically bypassed, and so on and so on. In some cases, it is possible that a screen will be encountered in this automatic navigation path that was already part of this automatic navigation sequence, which will result in the same set of screens being navigated through again (and again, and again, infinitely ...)
