Actually, the header in the BEGIN section determines the selection AND order of the elements to be output. It is split into the HDArr, which turn serves as the index into the associatve array RES when printed.
If field 1 (including delimiters) is found in the header, RES is filled with $0 with $1 and the field separator removed (effectively field 2).

cla_lin_berr.f(3)						      LAPACK							 cla_lin_berr.f(3)

NAME

       cla_lin_berr.f -

SYNOPSIS

   Functions/Subroutines
       subroutine cla_lin_berr (N, NZ, NRHS, RES, AYB, BERR)
	   CLA_LIN_BERR computes a component-wise relative backward error.

Function/Subroutine Documentation
   subroutine cla_lin_berr (integerN, integerNZ, integerNRHS, complex, dimension( n, nrhs )RES, real, dimension( n, nrhs )AYB, real, dimension(
       nrhs )BERR)
       CLA_LIN_BERR computes a component-wise relative backward error.

       Purpose:

	       CLA_LIN_BERR computes componentwise relative backward error from
	       the formula
		   max(i) ( abs(R(i)) / ( abs(op(A_s))*abs(Y) + abs(B_s) )(i) )
	       where abs(Z) is the componentwise absolute value of the matrix
	       or vector Z.

       Parameters:
	   N

		     N is INTEGER
		The number of linear equations, i.e., the order of the
		matrix A.  N >= 0.

	   NZ

		     NZ is INTEGER
		We add (NZ+1)*SLAMCH( 'Safe minimum' ) to R(i) in the numerator to
		guard against spuriously zero residuals. Default value is N.

	   NRHS

		     NRHS is INTEGER
		The number of right hand sides, i.e., the number of columns
		of the matrices AYB, RES, and BERR.  NRHS >= 0.

	   RES

		     RES is DOUBLE PRECISION array, dimension (N,NRHS)
		The residual matrix, i.e., the matrix R in the relative backward
		error formula above.

	   AYB

		     AYB is DOUBLE PRECISION array, dimension (N, NRHS)
		The denominator in the relative backward error formula above, i.e.,
		the matrix abs(op(A_s))*abs(Y) + abs(B_s). The matrices A, Y, and B
		are from iterative refinement (see cla_gerfsx_extended.f).

	   BERR

		     BERR is COMPLEX array, dimension (NRHS)
		The componentwise relative backward error from the formula above.
