/* 
 * PAUSE - prompt and wait for user signal to continue
 *
 * Usage:   pause [optional arguments]
 *
 * Note:
 * Default prompt is "press return key to continue" which is *evoked 
 * by calling pause with no arguments.  The word,
 * "continue", is replaced by any optional arguments handed to pause.
 * Thus, the command "pause do plot" will evoke the prompt,
 * "press return key to do plot".
