Preparing a Descriptor File
Problem descriptor files for use with FlexPDE are most easily prepared and edited using FlexPDE's built-in editor, which uses syntax highlighting to enhance the readability of the user's script. Recognized grammatical keywords are displayed in red, comments in green, and text strings in blue.
To begin a new descriptor file, simply click "File | New Script" from the FlexPDE main menu bar.
To edit an existing descriptor, click "File | Open Script" instead.
A convenient way to create a new descriptor is to start with a copy of an existing descriptor for a similar problem and to modify it to suit the new problem conditions.
FlexPDE's built-in editor is similar to the Windows Notepad editor and produces a pure ASCII text file without any imbedded formatting characters. Descriptor files can also be prepared using any ASCII text editor or any editor capable of exporting a pure ASCII text file. Descriptor files prepared with word processors that embed formatting characters in the text will cause FlexPDE to report parsing errors.
