Statements

11 -6
Use the DATA statement to specify the expressions that you can retrieve
with a READ statement (page 11 -31). If you use multiple expressions per
line, you must separate them with a comma.
Every time a READ statement is encountered the next consecutive
expression in the DATA statement is evaluated and assigned to the variable
in the READ statement. You can place DATA statements anywhere within
a program. They are not executed and do not cause an error.
DATA statements are chained and appear as one large DATA statement.
If at anytime all the data is read and you execute another READ statement,
the program terminates and the message
ERROR: NO DATA – IN LINE XX
prints to the console device. The module returns to Command mode.
Important: You cannot use the CHR operator (page 9 -16) in a DATA
statement.
