*  Purpose
*  =======
*
*  PB_INQUIRE returns wall or cpu time that has accumulated in timer I.
*
*  Arguments
*  =========
*
*  TMTYPE  (global input) CHARACTER
*          On entry, TMTYPE specifies what time will be returned as fol-
*          lows
*             = 'W': wall clock time is returned,
*             = 'C': CPU time is returned (default).
*
*  I       (global input) INTEGER
*          On entry, I specifies the timer to return.
