.SH NAME
intro \- introduction to FORTRAN library functions
.SH DESCRIPTION
.PP
This section describes those functions that are in the FORTRAN run time
library.  The functions listed here provide an interface from \fIf77\fP
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
.IR f77 (1).
.PP
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.
.PP
For efficiency, the SCCS ID strings are not normally included in the
.I a.out
file. To include them, simply declare
.nf

	external f77lid

.fi
in any
.I f77
module.
