"This column shows some simple but powerful techniques to make TCL data persistent in a text file and to parse it again from the file at a later point. We make use of TCL's flexible syntax to make the data files easily readable and even editable."
"A typical TCL script stores its internal data in lists and arrays (the two primary data structures in TCL). Suppose you want to write a TCL application that can save its data on disk and read it back again. For example, this allows your users to save a project and load it back later. You need a way to write the data from the place where it is stored internally (lists and arrays) to a file. You also need a way to read the data back into a running script."
"You can choose to store the data in a binary form or in a text file. This paper is limited to textual data file formats. We will look at a number of possible formats and how to parse them in TCL. In particular, we will show some simple techniques that make text file parsing a lot easier."
"This paper assumes that you are familiar with TCL, and that you have written at least a few simple scripts in TCL."
