READ ~ DATA
Example
Format READ <variable>[,<variable>] ...
5
DATA <constant>[,<constant>] ...
Abbreviated Format
REA. ~DA.
Explanation Like the INPUT and GET statements, the READ statement is used to submit data
to the computer for processing. However, unlike the other two statements, data is
not entered from the keyboard, but is instead held in the program itself with DATA
statements. More specifically, the function of the READ statement is to read suc-
cessive items of data into variables from a list of values which follows a DATA
statement. When doing this, there must be a one-to-one correspondence between
the variables of the READ statements and the data items specified in the DATA
statements. Quotation marks can be omitted for string data in DATA statements.
However, they cannot be omitted for null strings and strings including spaces.
(Example 1)
10 READ A,B,C,D
20 PRINT A;B;C;D
30 END
40 DATA 10,100,50,60
RUN
10 100 50 60
In this example, the values specified in the DATA statement are read into variables
A, B, C, and D by the READ statement, then the values of those variables are dis-
played.
(Example 2)
10 READ X$,A1,Z$
20 PRINT X$;A1;Z$
30 END
40 DATA A,1,C
As shown by the example above, string data included in DATA statements does
not need to be enclosed in quotation marks.
RUN
A 1C
The READ statement in this example picks successive data items from the list specified
in the DATA statement, then substitutes each item into the corresponding variable
in the list following the READ statement.
