3: .SH NAME
4: intro \- introduction to FORTRAN library functions
5: .SH DESCRIPTION
6: .PP
7: This section describes those functions that are in the FORTRAN run time
8: library. The functions listed here provide an interface from \fIf77\fP
9: programs to the system in the same manner as the C library does for C
10: programs. They are automatically loaded as needed by the Fortran compiler
11: .IR f77 (1).
12: .PP
13: Most of these functions are in libU77.a.
14: Some are in libF77.a or libI77.a.
15: A few intrinsic functions are described for the sake of completeness.
16: .PP
17: For efficiency, the SCCS ID strings are not normally included in the
18: .I a.out
19: file. To include them, simply declare

25: in any

27: module.
