Unassigning All Names
The restart command clears the Maple internal memory. The effects include
unassigning all names and unloading all packages. For more information,
refer to the ?restart help page.
Note: To use the examples in this manual, you may be required to use the
unassign or restart command between examples.
Valid Names
A Maple name must be one of the following.
• A sequence of alphanumeric and underscore (_) characters that begins
with an alphabetical character. Note: To enter an underscore character
in 2-D Math, enter a backslash character followed by an underscore
character, that is, \_.
• A sequence of characters enclosed in left single quotes (``).
Important: Do not begin a name with an underscore character. Maple re-
serves names that begin with an underscore for use by the Maple library.
Examples of valid names:
• a
• a1
• polynomial
• polynomial1_divided_by_polynomial2
• `2a`
• `x#y`
• `x y`
