Purpose:
'#include' pre-processor is used to make the file contents load inline.
This is used for code readability if smaller functions have to be grouped into separate files and called inline.

SYNTAX::
// The 'filename.sjs' just has the script without any function header or closing brace
// No need to load the include files, however they need to be placed in the scripts root directory (Cannot be in subfolders)
#include 'filename.sjs'[Make sure there are no spaces after the closing quote]

NOTE::
 - Available from LUI Desktop Version 1.2.331 and LUI Server Version 3.5.575
 - Make sure there are no blank spaces after the include declaration or else include will not get executed

Liquid UI Code:

Script File Name: SAPLSMTR_NAVIGATION.E0100.sjs       // Easy Access
----------------------------------------------------------------------------------------------------------------------------------------------
load("IW32_functions.sjs");

clearscreen();
inputfield( [1,1], "Order", [1,18],{ "name":"z_iw32_ordernum", "size":18, "required":true});
pushbutton([5,40],"Clear fields","?",{"process":clearData});
pushbutton([2,1],"Get Order Info [Syntax 1]","?",{"process":getOrderInfo_1});
comment([2,30],"This function does error handling, calls include function and returns to main function [Check Script Syntax]");
pushbutton([3,1],"Get Order Info [Syntax 2]","?",{"process":getOrderInfo_2});
comment([3,30],"The include function is being called entirely from the main function [Check Script Syntax]");
