The flexibility of Gamry’s Framework software is largely due to its foundation built around the EXPLAIN scripting language. All of the experiments run in Framework are written in EXPLAIN and the source code is available to the user for modification. Working with the scripting language is not difficult, but some computer programming experience, and especially experience with object-oriented languages, will be most beneficial. The following documents can assist the user with making some basic modifications to the scripts. A comprehensive syntax guide is built into the Framework software under the Help resources.
