GET
• A file currently activated
as
an
output
file cannot be specified in a GET state-
ment.
It
must first be closed,
then
reopened (in an OPEN statement
as
an input
file).
• Each value assigned
in
a GET statement must
be
of the same data
type
(arith-
meticor
character) as the corresponding variable.
• A GET statement referencing a currently closed file causes program execution
to
be
terminated.
Exampfe
A sample GET statement
is
as
shown:
0090
GET FL4,
X,
V, Z,
114.(4),
A(5),
0$,
EOF 620
Inthis
example, the values
in
file FL4 are assigned, respectively,
to
variables
X.
V,
Z,
the fourth and fifth elements
of
array A, and the character variable
0$.
On
end
of
file. the program branches
to
statement number 620 and closes FL4.
