Purpose
You want to return a function result in your JavaScript function
 

Solution
Use the function with parentheses e.g.

JavaScript

Remark
The notation without parentheses

JavaScript

is syntactically correct but returns the "toUpperCase" string function and not its result. In most cases this is not what you intend. It is possible (but rarely makes sense) to use the returned function in subsequent JavaScript calls; see the examples 3 and 4 below.

Example 1
GuiXT 

CallJS x = toUpper "abcde"
Message "&V[x]"

JavaScript 

		

		

		

		Example 2

CallJS x = mycall "&V[mytoupper]"  "abcde"
Message "&V[x]"

		
	
			
JavaScript


			
			

		

		

		

		Example 4

		GuiXT

CallJS mytoupper = toUpper
CallJS x = mycall "&V[mytoupper]"  "abcde"
Message "&V[x]"
