Keywords begin or separate portions of MAXScript commands. For example, one form of the if expression is:
if <expr> then <expr> [ else <expr> ]
In order for MAXScript to easily identify the various portions of the if expression, the words if, then and else are reserved keywords and can not be used as variable names or identifiers. So, for example, you cannot declare a variable or function called if. The following table lists all MAXScript reserved keywords. Click a reserved keyword to go to a description of its usage. In some cases, a keyword may have more additional meanings, depending on its context. This information is also summarized in MAXScript Grammar.
