C THIS SUBROUTINE EVALUATES THE AIRY FUNCTIONS AND THEIR
C DERIVATIVES FOR ANY REAL ARGUMENT WITHIN COMPUTER
C CAPABILITY, BY MEANS OF CHEBYSHEV SERIES APPROXIMATIONS.
C Z          -   THE ARGUMENT FOR WHICH THE FUNCTIONS ARE
C                TO BE EVALUATED.
C AI,BI      -   THE AIRY FUNCTIONS.
C AID,BID    -   THEIR RESPECTIVE DERIVATIVES.
C NFUNC      -   INDICATES WHICH OF THE FUNCTIONS ARE TO BE
C                CALCULATED.
C ISCAL      -   INDICATES WHETHER OR NOT SCALING IS
C                REQUIRED.
C FOUR RANGES OF ARGUMENT Z ARE CONSIDERED -
C (A)  Z .LE. -7.0
C (B)  -7.0 .LT. Z .LE. 0.0
C (C)  0.0 .LT. Z .LT. 7.0
C (D)  Z .GE. 7.0
C THE SUBROUTINES COEF1, COEF2, COEF3 AND COEF4 WHICH ARE
C CALLED BY THIS SUBROUTINE CORRESPOND RESPECTIVELY TO
C THESE FOUR RANGES.
C THE FUNCTIONS CALCULATED ARE AS FOLLOWS -
C IF NFUNC IS NEGATIVE  AID,BID.
C IF NFUNC = 0  ALL FOUR.
C IF NFUNC IS POSITIVE  AI,BI.
C ISCAL INDICATES WHETHER OR NOT IN RANGE (D) THE FOLLOWING
C SCALING IS TO BE CARRIED OUT -
C (AI,AID) = (AI,AID)*EXP(ZETA), (BI,BID) = (BI,BID)*EXP(-ZETA)
C WHERE ZETA = 2.0/3.0*Z**1.5
C IF ISCAL = 0 THEN THERE IS NO SCALING OTHERWISE SCALING
C AS ABOVE.
C IN (A) THE FINAL ACCURACY IS HEAVILY DEPENDENT ON THE
C ACCURACY TO WHICH THE SINE AND COSINE OF
C ANG = 2.0/3.0*(-Z)**1.5+PI/4 CAN BE COMPUTED.
C IF ANGLM .LT. ANG .LE. ANGUP THEN SOME ACCURACY MAY BE
C LOST. A NON FATAL ERROR WARNING IS GIVEN.
C IF ANG .GT. ANGUP A NON FATAL ERROR WARNING IS GIVEN AND
C THE FOUR FUNCTIONS ARE ASSIGNED THE VALUE ZERO.
C IN (D) IF ISCAL = 0 OVERFLOW IN EXP WILL OCCUR IF
C Z .GE. ZLIM. IN THIS CASE A NON FATAL ERROR WARNING IS
C GIVEN AND THE FOLLOWING VALUES ARE ASSIGNED -
C AI = AID = 0.0
C BI = BID = EXP(ZLIM).
C IF ISCAL .NE. 0 OVERFLOW WILL OCCUR IF
C Z .GT. ZUP = ZMAX**(2.0/3.0) WHERE ZMAX IS THE MAXIMUM
C REPRESENTABLE NUMBER ON THE COMPUTER. IN THIS CASE A
C NON FATAL ERROR WARNING IS GIVEN AND THE FOUR FUNCTIONS
C ARE ASSIGNED THE VALUE ZERO.
C NOUT IS THE OUTPUT CHANNEL USED.
C THE MACHINE DEPENDENT CONSTANTS (VALUES BEING ASSIGNED BY
C APPROPRIATE DATA STATEMENTS) ARE -
C IN COEF1  -  ANGLM,ANGUP AND NOUT.
C IN COEF4  -  ZLIM,ZUP AND NOUT.

C THIS SUBROUTINE EVALUATES THE AIRY FUNCTIONS AND THEIR
C DERIVATIVES FOR ANY REAL ARGUMENT WITHIN COMPUTER
C CAPABILITY, BY MEANS OF CHEBYSHEV SERIES APPROXIMATIONS.
C Z          -   THE ARGUMENT FOR WHICH THE FUNCTIONS ARE
C                TO BE EVALUATED.
C AI,BI      -   THE AIRY FUNCTIONS.
C AID,BID    -   THEIR RESPECTIVE DERIVATIVES.
C NFUNC      -   INDICATES WHICH OF THE FUNCTIONS ARE TO BE
C                CALCULATED.
C ISCAL      -   INDICATES WHETHER OR NOT SCALING IS
C                REQUIRED.
C FOUR RANGES OF ARGUMENT Z ARE CONSIDERED -
C (A)  Z .LE. -7.0
C (B)  -7.0 .LT. Z .LE. 0.0
C (C)  0.0 .LT. Z .LT. 7.0
C (D)  Z .GE. 7.0
C THE SUBROUTINES COEF1, COEF2, COEF3 AND COEF4 WHICH ARE
C CALLED BY THIS SUBROUTINE CORRESPOND RESPECTIVELY TO
C THESE FOUR RANGES.
C THE FUNCTIONS CALCULATED ARE AS FOLLOWS -
C IF NFUNC IS NEGATIVE  AID,BID.
C IF NFUNC = 0  ALL FOUR.
C IF NFUNC IS POSITIVE  AI,BI.
C ISCAL INDICATES WHETHER OR NOT IN RANGE (D) THE FOLLOWING
C SCALING IS TO BE CARRIED OUT -
C (AI,AID) = (AI,AID)*EXP(ZETA), (BI,BID) = (BI,BID)*EXP(-ZETA)
C WHERE ZETA = 2.0/3.0*Z**1.5
C IF ISCAL = 0 THEN THERE IS NO SCALING OTHERWISE SCALING
C AS ABOVE.

C AI = AID = 0.0
C BI = BID = EXP(ZLIM).
C IF ISCAL .NE. 0 OVERFLOW WILL OCCUR IF
C Z .GT. ZUP = ZMAX**(2.0/3.0) WHERE ZMAX IS THE MAXIMUM

C ARE ASSIGNED THE VALUE ZERO.
