The IMSL libraries MATH, STAT, and SFUN have been installed on AIX/370. The libraries are designed for use with IBM's VS-FORTRAN on the 3090 with the vector facility. Manuals for the subroutine library are available on reserve in the Robert E. Kennedy Library Reserve Room. Accessing the library is accomplished as follows: fvs -xa [optional flags] main.f -limslib -limslblas [optional flags] Where "main.f" is the name of the calling program which is provided by the user. The "-xa" parameter is required to generate an "XA" compatible object module. For publication information, please see the imsl entry under the "whatson" command.
