+/*  ======= */
+
+/*  DLABAD takes as input the values computed by DLAMCH for underflow and */
+/*  overflow, and returns the square root of each of these values if the */
+/*  log of LARGE is sufficiently large.  This subroutine is intended to */
+/*  identify machines with a large exponent range, such as the Crays, and */
+/*  redefine the underflow and overflow limits to be the square roots of */
+/*  the values computed by DLAMCH.  This subroutine is needed because */
+/*  DLAMCH does not compensate for poor arithmetic in the upper half of */
+/*  the exponent range, as is found on a Cray. */
+
+/*  Arguments */
+/*  ========= */
+
+/*  SMALL   (input/output) DOUBLE PRECISION */
+/*          On entry, the underflow threshold as computed by DLAMCH. */
+/*          On exit, if LOG10(LARGE) is sufficiently large, the square */
+/*          root of SMALL, otherwise unchanged. */

+/*  LARGE   (input/output) DOUBLE PRECISION */
+/*          On entry, the overflow threshold as computed by DLAMCH. */
+/*          On exit, if LOG10(LARGE) is sufficiently large, the square */
