SUBROUTINE PZSEPRREQ( HETERO, NIN, MEM, MEMSIZE, NOUT, ISEED,

*
* -- ScaLAPACK routine (@(MODE)version *TBA*) --
* University of California, Berkeley and
* University of Tennessee, Knoxville.
* October 21, 2006
*
IMPLICIT NONE

* .. Scalar Arguments ..
CHARACTER HETERO

INTEGER ISEED( 4 )
COMPLEX*16 MEM( MEMSIZE )
*
* Purpose
* =======
*
* PZSEPRREQ performs one request from the input file 'SEPR.dat'
* A request is the cross product of the specifications in the
* input file. It prints one line per test.
*
* Arguments
* =========
*
* NIN (local input) INTEGER
* The unit number for the input file 'SEPR.dat'
*
* MEM (local input ) COMPLEX*16 ARRAY, dimension MEMSIZE
* Array encompassing the available single precision memory
*
* MEMSIZE (local input) INTEGER
* Size of MEM array
*
* NOUT (local input) INTEGER
* The unit number for output file.
* NOUT = 6, output to screen,
* NOUT = 0, output to stderr.
* NOUT = 13, output to file, divide thresh by 10
* NOUT = 14, output to file, divide thresh by 20
* Only used on node 0.
* NOUT = 13, 14 allow the threshold to be tighter for our
* internal testing which means that when a user reports
* a threshold error, it is more likely to be significant.
*
* ISEED (global input/output) INTEGER array, dimension 4
* Random number generator seed
*
* NTESTS (global input/output) INTEGER
* NTESTS = NTESTS + tests requested
*
* NSKIPPED (global input/output) INTEGER
* NSKIPPED = NSKIPPED + tests skipped
*
* NNOCHECK (global input/output) INTEGER
* NNOCHECK = NNOCHECK + tests completed but not checked
*
* NPASSED (global input/output) INTEGER
* NPASSED = NPASSED + tests which passed all checks
*
* INFO (global output) INTEGER
* 0 = test request ran
* -1 = end of file
* -2 = incorrect .dat file
*
* .. Parameters ..
