Warning Messages
|
|
Maple produces various informative warning messages when executing a command. Some of the instances where warning message are displayed are discussed below. For examples of warning messages, see the Examples section.
|
|
•
|
Modules and procedures can have implicitly declared local variables. A warning message is displayed when a variable is implicitly declared, indicating the location of the implicit declaration. See Implicit Local Variables for more information.
|

|
Maple commands can return qualitative information about a given expression. For example, the Roots command returns the roots of a given expression. If there is an infinite number of roots, a warning message is displayed and a few sample points are returned.

Warning Messages in Help Pages

|
|
|
Most help pages in the Maple help system do not display warning messages. For illustrative purposes, however, warning messages are displayed in a few help pages.
