DATA Purpose
Use the DATA statement to specify the expressions that you can retrieve with a
READ statement. If multiple expressions per line are used, 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 considered chained
and appear as one large DATA statement. If at anytime all the data is read and
another READ statement is executed, the program terminates and the message
ERROR: NO DATA - IN LINE XX prints to the console device. The module
returns to Command mode.

DIM Purpose
Use the DIM statement to reserve storage for matrices. The storage area is first
assumed to be zero. Matrices in the BASIC module may have only one dimension
and the size of the dimensioned array may not exceed 254 elements.
IMPORTANT
You cannot use the CHR operator in a DATA statement.
