          SUBROUTINE GAMLIM (XMIN, XMAX)
    C***BEGIN PROLOGUE  GAMLIM
    C***PURPOSE  Compute the minimum and maximum bounds for the argument in
    C            the Gamma function.
    C***LIBRARY   SLATEC (FNLIB)
    C***CATEGORY  C7A, R2
    C***TYPE      SINGLE PRECISION (GAMLIM-S, DGAMLM-D)
    C***KEYWORDS  COMPLETE GAMMA FUNCTION, FNLIB, LIMITS, SPECIAL FUNCTIONS
    C***AUTHOR  Fullerton, W., (LANL)
    C***DESCRIPTION
    C
    C Calculate the minimum and maximum legal bounds for X in GAMMA(X).
    C XMIN and XMAX are not the only bounds, but they are the only non-
    C trivial ones to calculate.
    C
    C             Output Arguments --
    C XMIN   minimum legal value of X in GAMMA(X).  Any smaller value of
    C        X might result in underflow.
    C XMAX   maximum legal value of X in GAMMA(X).  Any larger value will
    C        cause overflow.
