NAME

intro − introduction to FORTRAN library functions

DESCRIPTION

This section describes those functions that are in the Fortran run time library, libU77.  The functions listed here provide an interface from f77 programs to the system in the same manner as the C library does for C programs.  The +U77 option to the Fortran compiler f77(1) causes it to recognize and load the libU77 functions.
