Introduction to script files
A script file is a standard text file that contains special window building commands. It must begin with the .SCRIPT command. The recommended extension for a script file is .wsc.
Storing all the window building information in a script file enables you to maintain your windows external to your program. You can do things like redefine border attributes, change shortcuts, and redefine field characteristics without ever touching your code, which means you don’t have to recompile or relink.
You can create your script file with any text editor, using the commands described in Using the script commands. You can also use Composer to create and modify script files interactively (see Composer).
