Values

-- System variable: values Initial value: []

values is a list of all bound user variables (not Maxima options or switches). The list comprises symbols bound by :, or ::.

If the value of a variable is removed with the commands kill, remove, or remvalue the variable is deleted from values.

See functions for a list of user defined functions.

Examples:

First, values shows the symbols a, b, and c, but not d, it is not bound to a value, and not the user function f. The values are removed from the variables. values is the empty list.

          (%i1) [a:99, b::a-90, c:a-b, d, f(x):= x^2];
                                                            2
          (%o1)                     [99, 9, 90, d, f(x) := x ]
          (%i2) values;
          (%o2)                              [a, b, c]
          (%i3) [kill(a), remove(b,value), remvalue(c)];
          (%o3)                          [done, done, [c]]
          (%i4) values;
          (%o4)                                 []

There are also some inexact matches for values. Try ?? values to see them.

(%o1)                                true
(%i2)
