00012 *  Purpose
00013 *  =======
00014 *
00015 *  ZERRGE tests the error exits for the COMPLEX*16 routines
00016 *  for general matrices.
00017 *
00018 *  Note that this file is used only when the XBLAS are available,
00019 *  otherwise zerrge.f defines this subroutine.

00022 *  =========
00023 *
00024 *  PATH    (input) CHARACTER*3
00025 *          The LAPACK path name for the routines to be tested.
00026 *
00027 *  NUNIT   (input) INTEGER
00028 *          The unit number for output.
