ZLAG2C converts a COMPLEX*16 matrix, SA, to a COMPLEX matrix, A.


 RMAX is the overflow for the SINGLE PRECISION arithmetic


 ZLAG2C checks that all the entries of A are between -RMAX and


 RMAX. If not the convertion is aborted and a flag is raised.


 This is an auxiliary routine so there is no argument checking.

M

          M is INTEGER


          The number of lines of the matrix A.  M >= 0.

N

          N is INTEGER


          The number of columns of the matrix A.  N >= 0.

A

          A is COMPLEX*16 array, dimension (LDA,N)


          On entry, the M-by-N coefficient matrix A.

LDA

          LDA is INTEGER


          The leading dimension of the array A.  LDA >= max(1,M).

SA

          SA is COMPLEX array, dimension (LDSA,N)


          On exit, if INFO=0, the M-by-N coefficient matrix SA; if


          INFO>0, the content of SA is unspecified.

LDSA

          LDSA is INTEGER


          The leading dimension of the array SA.  LDSA >= max(1,M).

INFO

          INFO is INTEGER


          = 0:  successful exit.


          = 1:  an entry of the matrix A is greater than the SINGLE


                PRECISION overflow threshold, in this case, the content


                of SA in exit is unspecified.
