Reserved words

The words PowerBuilder uses internally are called reserved words and cannot be used as identifiers. If you use a reserved word as an identifier, you get a compiler warning. Reserved words that are marked with an asterisk (*) can be used as function names.

The PowerBuilder system class also includes private variables that you cannot use as identifiers. If you use a private variable as an identifier, you get an informational message and should rename your identifier.

If you are deploying a DataWindow to the Web, you cannot use JavaScript reserved words to name fields or bands in the DataWindow object. The list of reserved words is available on the Sun Microsystems Web site..
