*
*  Purpose
*  =======
*
*  PSBLAS2TSTCHKE tests the error exits of the Level 2 PBLAS.
*
*  Arguments
*  =========
*
*  LTEST   (global input) LOGICAL array
*          On entry, LTEST is an array of dimension at least 7 (NSUBS).
*             If LTEST( 1 ) is .TRUE., PSGEMV will be tested;
*             If LTEST( 2 ) is .TRUE., PSSYMV will be tested;
*             If LTEST( 3 ) is .TRUE., PSTRMV will be tested;
*             If LTEST( 4 ) is .TRUE., PSTRSV will be tested;
*             If LTEST( 5 ) is .TRUE., PSGER  will be tested;
*             If LTEST( 6 ) is .TRUE., PSSYR  will be tested;
*             If LTEST( 7 ) is .TRUE., PSSYR2 will be tested;
*
*  INOUT   (global input) INTEGER
*          On entry,  INOUT  specifies  the unit number for output file.
*          When INOUT is 6, output to screen,  when INOUT = 0, output to
*          stderr. INOUT is only defined in process 0.
*
*  NPROCS  (global input) INTEGER
*          On entry, NPROCS specifies the total number of processes cal-
*          ling this routine.
