NAME
intro − introduction to FORTRAN library functions
DESCRIPTION
This section describes those functions that are in the FORTRAN run time library. 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. They are automatically loaded as needed by the Fortran compiler f77(1).
Most of these functions are in libU77.a. Some are in libF77.a or libI77.a. A few intrinsic functions are described for the sake of completeness.
