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