In Section 7.10 modify the 3^rd, 4^th, and last paragraphs as shown in blue.

Built-in methods, unlike system tasks, can not be redefined by users via PLI tasks. Thus, only functions that

users should not be allowed to redefine are good candidates for built-in method calls.

In general, a built-in method is preferred over a system task when a particular functionality applies to all data types, or

it applies to a specific data type. For example:

A build-in method can only be associated with a particular data type, therefore, if some functionality is a simple side

effect (i.e., $stop or $reset) or it operates on no specific data (i.e., $random) then a system task must be used.
