The ShowSteps command displays the sequence of steps of the problem from its initial state to its current state.  The display is accomplished using calls to print; the value returned by ShowSteps is NULL.  Thus, the history variables, %, %%, and %%%, are not modified by this command.

This command can be applied interactively by using the DiffTutor, IntTutor, or LimitTutor.

If called with no arguments, the current problem is displayed. To designate a problem the current problem, create a new problem (see Rule or Hint) or use the GetProblem command.

If expr is a positive integer, the corresponding problem is displayed.

If expr is the keyword all, the current states of all problems from the current session are displayed.  Note: Problems that have been cleared by a call to Clear are not displayed.

If expr is the output from a previous call to Rule or GetProblem (with the internal option), or the left-hand side of such output, the current state of that problem is displayed.

The showrules option specifies whether or not to display the rules which have been applied at each step.

Unlike for the Show and ShowIncomplete commands, a subproblem label is not valid input to this command.

Maple returns an error if you attempt to display a problem that has been cleared by a call to the package routine Clear.

This command does not change which problem is designated the current problem.
