Preparing a Descriptor File

Problem descriptor files for use with FlexPDE are most easily prepared and edited using FlexPDE's built-in editor.

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.

The built-in editor in FlexPDE uses syntax highlighting to enhance the readability of the user's script.  Recognized keywords are displayed in red, comments in green, and text strings in blue.
