/*  Purpose */
/*  ======= */

/*  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. */

/*  Arguments */
/*  ========= */

/*  M       (input) INTEGER */
/*          The number of lines of the matrix A.  M >= 0. */

/*  N       (input) INTEGER */
/*          The number of columns of the matrix A.  N >= 0. */

/*  A       (input) COMPLEX*16 array, dimension (LDA,N) */
/*          On entry, the M-by-N coefficient matrix A. */

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

/*  SA      (output) 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    (input) INTEGER */
/*          The leading dimension of the array SA.  LDSA >= max(1,M). */

/*  INFO    (output) 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. */
