\b7 is the UNIX Fortran 77 compiler. It accepts several
Arguments whose names end with `.f' are taken to be Fortran
77 source programs; they are compiled, and each object pro-
gram is left on the file in the current directory whose name
is that of the source with `.o' substituted for '.f'.
Arguments whose names end with `.F' are also taken to be
Fortran 77 source programs; these are first processed by the
C preprocessor before being compiled by _
\bf_
\b7_
\b7.
Arguments whose names end with `.r' or `.e' are taken to be
Ratfor or EFL source programs respectively; these are first
transformed by the appropriate preprocessor, then compiled
Arguments whose names end with `.c' or `.s' are taken to be
C or assembly source programs and are compiled or assembled,
The following options have the same meaning as in _

Define the _

\be to the C preprocessor, as if by
`#define'. If no definition is given, the name is
defined as "1". (`.F' suffix files only).
`#include' files whose names do not begin with `/' are
always sought first in the directory of the _

ment, then in directories named in -

directories on a standard list. (`.F' suffix files

-
\b-S

language output on corresponding files suffixed `.s'.
The following options are peculiar to _

\bd Used for debugging the compiler.
-

default integer constants and variables short. (-

\b4 is
the standard value of this option). All logical quanti-
-
\b-q
\bq Suppress printing of file names and program unit names
-

transforming it with the Ratfor or EFL preprocessor.
-
\b-o
\bon
\bne
\bet
\btr
\bri
\bip
\bp
-
\b-1
\b1 Compile DO loops that are performed at least once if
reached. (Fortran 77 DO loops are not performed at all
if the upper limit is smaller than the lower limit.)
-
\b-r
\br8
\b8 Treat all floating point variables, constants, func-
tions and intrinsics as double precision and all com-
plex quantities as double complex.
-
\b-u
\bu Make the default type of a variable `undefined' rather
than using the default Fortran rules.
-
\b-v
\bv Print the version number of the compiler, and the name
of each pass as it executes.

\b-C
\bC Compile code to check that subscripts are within
declared array bounds. For multi-dimensional arrays,
only the equivalent linear subscript is checked.
-
\b-F
\bF Apply the C preprocessor to `.F' files, and the EFL, or
Ratfor preprocessors to `.e' and `.r' files, put the
result in the file with the suffix changed to `.f', but

Make static tables in the compiler bigger. The compiler
will complain if it overflows its tables and suggest
you apply one or more of these flags. These flags have
q
\bq Maximum number of equivalenced variables. Default
x
\bx Maximum number of external names (common block
names, subroutine and function names). Default is
s
\bs Maximum number of statement numbers. Default is
c
\bc Maximum depth of nesting for control statements
(e.g. DO loops). Default is 20.
n
\bn Maximum number of identifiers. Default is 1009.
-
\b-U
\bU Do not convert upper case letters to lower case. The
default is to convert Fortran programs to lower case
except within character string constants.
Other arguments are taken to be either loader option argu-
ments, or F77-compatible object programs, typically produced
by an earlier run, or perhaps libraries of F77-compatible
routines. These programs, together with the results of any
compilations specified, are loaded (in the order given) to
produce an executable program with name `a.out'.
Programs compiled with _
