FORTRAN-SO
Introduction
To
FORTRAN
Statement
20,
the
FORMAT
statement,
indicates
the
'PNAME'
field will be a
string
of
characters
of
variable
length, as in
the
FORMAT
statement
labeled 10.
The
name
will be followed by five
blanks
(5X)
and
then
the
batting
average will be
printed.
The
'A
VG'
field consists
of
four
floating-point
digits --
one
integer
digit
and
three
decimal
digits.
1.1.6 Program Termination
The
final
statement
terminates
the
program.
The
END
statement
is
an
indicator
to
the
FORTRAN
compiler
that
it
hasTeached
the
end
of
the
program.
Every
program
unit
must
be
terminated
by
an
END
statement.
1.2 Summary Of
FORTRAN·SO
Statements
The
statements
available
in
FORTRAN-80
are
listed below
according
to
their
main
classifications.
These
include all
statements
available in
the
FORTRAN
77 subset
and
some
from
the
FORTRAN
77
full language.
To
simplify
comparison,
the
statements
are
listed in
the
same
sequence
as in Section 7
of
the
ANSI
standard.
All
chapter
references
are
to
this
manual,
however,
not
to
the
ANSI
standard.
Statements
are
classified as executable
or
nonexecutable.
Executable
statements
do
calculations,
read
or
write
110
data,
and
control
program
execution.
Nonex-
ecutable
statements
define
the
characteristics
or
value
of
data
and
define
program
units.
