12.12 Tailoring the DEFAULT_SCRIPT
The standard DEFAULT_SCRIPT shipped with LANSA for the Web is extensive and contains some functions which are not essential for all applications. Consequently it is possible to tailor the script to contain only the functions required by your application. This will result in improved execution performance because the volume of data being transferred to the browser is reduced.
A tailored script can be created for a specific process and named
<process name>_SCRIPT
This script will be used when the specific process is executed.
If you wish to save your tailored script as DEFAULT_SCRIPT, it is strongly recommended that you first save a back up version of the full script.
