INPUT # ( )(input)
Reads out data from BRD file.
Format:
INPUT # <logical
number>,
«data
element
number»,
<variable> [,<variable>, ... ]
Abbreviated form:
1.#(
)
Explanation:
• The data
of
the position designated by the data element number are read from the
file cross-opened by the
XOPEN
# statement into the designated variable.
It
makes no difference if the variable
is
an array variable.
• The file which reads out the
data
becomes the file set to <logical
number>
by
the
XOPEN
# statement.
• In the same way as for the
READ
-
DATA
statements, an error
will
be generated
if the data and the
<variable>
data type do not coincide.
• The end
of
the file data can be detemined by
EOF
function.
• The data element position is from 1 - n.

CD,
@ and @ data positions
indicated by Z in the figure are read in and displayed in order. When the data
end, the

# function becomes truth at line 40, and jumps to line 80.
