    20  C         FOR PROPER CHOICES OF C1, C2, AIRY AND DAIRY WHERE AIRY IS
    21  C         AN AIRY FUNCTION AND DAIRY IS ITS DERIVATIVE.

    28  C         MCONJ=SIGN OF AIMAG(Z), BUT IS AMBIGUOUS WHEN Z IS REAL AND
    29  C         MUST BE SPECIFIED. IPMTR=0 RETURNS ALL PARAMETERS. IPMTR=
    30  C         1 COMPUTES ALL EXCEPT ASUM AND BSUM.
