READ
Statement
READ variable[,uariable,..
.I
Reads values from a DATA statement and assigns them t o
variables.
BASIC assigns values from the DATA statement on a one-to-one
basis. The first time READ is executed, the first value in the
first DATA statement is assigned to the first variable; the second
time, the second value is assigned to the second variable, and so
on.
A single READ may access
1 or more DATA statements, or sev-
eral READS may access the same DATA statement. If a program
contains multiple DATA statements, BASIC reads them in the or-
der they appear.
The values read must agree with the variable types specified in
a list of variables; otherwise, a "Syntax error" occurs.
If the number of variables in the READ statement exceeds the
number of elements in the DATA statement(s1, BASIC returns an
"Out of DATA" error message. If the number of variables speci-
fied is less than the number of elements in the DATA state-
ment(s), the next READ statements begin reading data at the
first unread element.
To reread DATA statements from the start, use the RESTORE
statement.
Example
READ T
reads a numeric value from a DATA statement and assigns it to
variable T.
