integer , it will be rounded to the nearest integer.
If the value specified does not lie between 0 and 255, it will be
output modulo 256. In other words, 256would be sentas 0, 257as
1,258 as 2, 259 as 3, etc.

Reading from Data Files
The INPUT# and GET statements are used to read data from
cassette data files. INPUT# will accept data from the cassette data

variables names in its parameter li st.
The following configuration is used with INPUT#:
INPUT
#channe l { ~} variable, . ..
The channel must have been opened previously for input. The
variables will accept the data values input.
INPUT# will retrieve data from the input device specified. This
data
will consi st of ASCII characters followed by the ASCII end-
of-line character. The EOL character will end input to the
variable specified.
INPUT# will interpret the data being read as e ither numeric or
string--depending on the type of variables used as parameters.
When a numeric variable is specified, the data being input will
be interpr eted as numeric data.
