Xbasic .aex files
Specify a comma delimited list of .aex files. .aex files contain compiled Xbasic functions that can be used in any of the server-side event handlers.
You do not have to list .aex files here if you have specified the .aex files in the Project Properties dialog, 'Aex files' property. If you specify .aex files here, they will be automatically added to the 'Aex files' property in the Project Properties.
The Project Properties dialog is opened from a button on the Web Control Panel.
