Refer to the OPEN statement description (6.8.1) for more information
on how the GET statement is used with the OPEN statement.
6.8.8 READ Statement
The READ statement directs the system to read from a list of values
built in a data block by a DATA statement. A READ statement is not
legal without at least one DATA statement.
A READ statement causes the variables listed in it to be given the
value of the next expression in the next DATA statement. BASIC has
a pointer to keep track of the data being read by the READ
statement. Each time the READ statement requests data, BASIC
retrieves the next expression indicated by the data pointer.
The READ statement has the following format:
READ variable_1,variable_2,...,variable_N
where:
variable_1 through variable_N = the value(s) listed in the DATA
statements
The variables can be simple (A%) or subscripted (A%(4)) and can be
any of the five variable types: integer, double integer, real, string,
and boolean. All variables should be separated by commas. String
variables should be enclosed within single or double quotes.
The following is a valid READ statement:
10 READ A%,B%,C$,D%(5)
6.8.9 DATA Statement
The DATA statement has the following format:
DATA expression_1, expression_2,... ,expression_n
where:
expression_1 to expression_n =
expression that, after evaluation, is loaded into
the corresponding variable in a READ
statement when the READ is executed
The data type of the expression in the DATA statement must be the
same as the data type of the variable that corresponds to it in the
READ statement.
The program will run faster with READ and DATA statements as
opposed to the INPUT statement simply because the system does
not have to wait the extra time it takes for the system to stop and
request data. The data is already within the program.
The DATA statements may be formatted with any number of
expressions as long as the same number is being requested by the
READ statements:
10 READ A,B,C,D,E,F
20 ...
30 ...
40 ...
