Nature of problem:
The program ASYPCK has been used extensively to obtain asymptotic solutions of the second-order differential equations of the type encountered in electron-ion and electron-atom scattering (for example in conjunction with the programs IMPACT and RMATRX. With increased usage a number of improvements and additional facilities have been developed and incorporated in this new version of ASYPCK, known as ASYPCK2. New features include a version for use on CRAY machines, a double precision version for use on IBM machines and an automatic setting of the Fox-Goodwin parameter MFG.

Solution method:
As ASYPCK. (Comm. Phys. Commun. 19(1980)103.)

The program ASYPCK2 is provided in a form which must be pre-processed by a program ASYPRO2, which is an updated version of the program ASYPRO.

Running time:
As ASYPCK, except that when running the special CRAY version on CRAY machines, in which case considerable time saving may be achieved.
