Basic JSL Syntax
A JSL script is a series of expressions. Each expression is a section of JSL code that accomplishes a task. JSL expressions hold data, manipulate data, and send commands to objects.
Many expressions are nested message names, with message contents enclosed in parentheses:
Message Name ( argument 1, argument 2, ... );
The meaning of JSL names depends on the context. The same name might mean one thing in a data table context and something entirely different in a function context. See Rules for Name Resolution in JSL Building Blocks for more information.
Almost anything that follows certain punctuation rules, such as matching parentheses, is a valid JSL expression. For example:
win = New Window( "Window Example",
	<<Modal,
	Text Box( "Hello, World" ),
	Text Box( "-----" ),
	Button Box( "OK" )
);
Note the following:
•
Names can have embedded spaces. See Names in JSL Building Blocks for more information.
•
Message contents are enclosed in parentheses, which must be balanced. See Parentheses in JSL Building Blocks.
•
Items are separated by commas. See Commas in JSL Building Blocks.
•
JSL is not case sensitive; you can type “text box();” or “Text Box()”.
•
Messages are commonly nested inside other messages.
