pointer will point at the first value in the DATA list. As values
from the DATA list are assigned to variables in the READ
statement,
the pointer will move sequentially to each successive
item in the DATA list.
The values from the DATA list must match the type of variable to
which they are assigned in the READ statement. In other words, a
string
value can not be assigned to a numeric or vice versa.
The
RESTORE statement is used to reset the DATA list. In
Illustration 3-4, note the use of the RESTORE statement. After
DATA list values have been read into A, B, C, D, and E in line 500 ,
a RESTORE statement is executed . This causes the DATA list
pointer to be reset to the beginning of the DATA list.
Outputting Data
In some of our preceding examples, we touched upon the use of
the PRI NT statement to display data. The PRI NT statement can be
used
to display both numeric and string data.
The
following program statement,
100 PRINT "Vendor List"
would display the following at the current cursor position.
Vendor List
The first
item in a PRINT statement is displayed at the cursor's
current location.
Several strings can be displayed on the same line with a single
PRINT
statement by separating the string constants or variables
in the PRINT statement with commas. The following statements,
050 DIM A$(10)
100
LET A$ = "John"
200 PRINT A$, "Bill", "Peter"
