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