      FUNCTION AIE (X)
C***BEGIN PROLOGUE  AIE
C***PURPOSE  Calculate the Airy function for a negative argument and an
C            exponentially scaled Airy function for a non-negative
C            argument.
C***LIBRARY   SLATEC (FNLIB)
C***CATEGORY  C10D
C***TYPE      SINGLE PRECISION (AIE-S, DAIE-D)
C***KEYWORDS  EXPONENTIALLY SCALED AIRY FUNCTION, FNLIB,
C             SPECIAL FUNCTIONS
C***AUTHOR  Fullerton, W., (LANL)
C***DESCRIPTION
C
C AIE(X) computes the exponentially scaled Airy function for
C non-negative X.  It evaluates AI(X) for X .LE. 0.0 and
C EXP(ZETA)*AI(X) for X .GE. 0.0 where ZETA = (2.0/3.0)*(X**1.5).
