/*
*  Purpose
*  =======
*
*  PB_topget_ returns the row, column or all broadcast and combine topo-
*  logies.
*
*  Arguments
*  =========
*
*  ICTXT   (local input) INTEGER
*          On entry,  ICTXT  specifies the BLACS context handle, indica-
*          ting the global  context of the operation. The context itself
*          is global, but the value of ICTXT is local.
*
*  OP      (global input) pointer to CHAR
*          On input,  OP  specifies  the BLACS operation defined as fol-
*          lows:
*             OP = 'B' or 'b', BLACS broadcast operation,
*             OP = 'C' or 'c', BLACS combine operation.
*
*  SCOPE   (global input) pointer to CHAR
*          On entry, SCOPE specifies the scope of the BLACS operation as
*          follows:
*             SCOPE = 'R' or 'r', rowwise broadcast or combine,
*             SCOPE = 'C' or 'c', column broadcast or combine,
*             SCOPE = 'A' or 'a', all broadcast or combine.
*
*  TOP     (global output) pointer to CHAR
*          On exit, TOP  is a character string specifying the  BLACS to-
*          pology current in use for the given operation specified by OP
*          and SCOPE.
