This section describes those functions that are in the FORTRAN run time
library.  The functions listed here provide an interface from 
.PN 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
.MS 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.

For efficiency, the SCCS ID strings are not normally included in the
.PN a.out
file. To include them, simply declare the following in any 
.PN f77
module:
.EX
external f77lid
