 DGET32 tests DLASY2, a routine for solving

         op(TL)*X + ISGN*X*op(TR) = SCALE*B

 where TL is N1 by N1, TR is N2 by N2, and N1,N2 =1 or 2 only\&.
 X and B are N1 by N2, op() is an optional transpose, an
 ISGN = 1 or -1\&. SCALE is chosen less than or equal to 1 to
 avoid overflow in X\&.

 The test condition is that the scaled residual

 norm( op(TL)*X + ISGN*X*op(TR) = SCALE*B )
      / ( max( ulp*norm(TL), ulp*norm(TR)) * norm(X), SMLNUM )

 should be on the order of 1\&. Here, ulp is the machine precision\&.
 Also, it is verified that SCALE is less than or equal to 1, and
 that XNORM = infinity-norm(X)\&.
