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. Message contents are 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”.
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" )
);
Notes:
• Names can have embedded spaces. See “JSL Rules for Names”.
• Message contents are enclosed in parentheses, which must be balanced. See “Parentheses”.
• Items are separated by commas. See “Commas”.
• JSL is not case sensitive; you can type “text box();” or “Text Box()”.
• Messages are commonly nested inside other messages.
