I have seen in a lot of code things lik
data 1,4,2,6,3....
data 2,6,3,7,2....
surely once you introduce another data command it runs over the original list and you cannot read it again. If not, how would you read multiple data commands?

data 1,2,3,4,5
data 5,4,3,2,1

?????

No, it reads every piece of data.

for example, if you'd use something like

data 1,2,3,4
data 5,6,7,8

and read it, you'd get 1,2,3,4,5,6,7,8 as values. Experiment with it, maybe try out this code.

dim data(10)
for i=0 to 9
read data(i)
print data(i)
next i

data 1,2,3,4,5
data 6,7,8,9,10

Whatever I did I didn't do it!

then if you want to read some part of the data over again you do this

for i=0 to 3
read x(i)
next i
restore half_of_data
for i=0 to 1
read y(i)
next i
data 123,456
:half_of_data
data 789,101

the first time the code will read all four numbers, and the second time just the numbers in the data statement after the label half_of_data, the restore command resets the reading to the position indicated by the label name in restore,so..
x(0)=123
x(1)=456
x(2)=789
x(3)=101
and
y(0)=789
y(1)=101

hope thats some help.

Oh! and if you just want to read the data over again from the start then just use the instruction RESTORE on it`s own.
