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 at https://docs.microsoft.com/en-us/scripting/javascript/reference/javascript-reserved-words.
