READ AND DATA
When it is necessary to enter a lot of information or data into the computer, using the
INPUT
statement can be very time consuming. To help out use the
READ
and
DATA
commands.
Example
:
10 DATA 10,60,70,80,90
20 READ A,B,C,D,E
30 PRINT A;B;C;D;E
RUN
10 60 70 80 90
The
READ
statement consists of a list of variable names with commas between each variable.
The
DATA
statement consists of a list of expressions separated by commas. These
expressions can be either numeric or strings. The
READ
statement makes the computer
look up the value of its variables from the
DATA
statement. When the computer goes
to
READ
first it will assign the first expression from the
DATA
list. The next time it goes
to
READ
it will assign the second value and so on. If the
READ
runs out of
DATA
you
will get
"? OUT OF DATA ERROR."
RESTORE
If you want to use the same data later on in the program you can do so by using the
RESTORE
statement.
