Is it possible to have a command line like ptoff(1,2 and 3,4 and 5,6
and so forth or would that not work? I dont have my calculator so I could not do this myself. |

Nope.
You could use a list and a loop though. Or just multiple pt-off statements. |

Can you give an example?
What I want to be able to do is take points off on a black screen to make words. But I know you cant recall a certain part of a list.

OK, you understand the concept of drawing one white pixel, right?
Now, supposing you want to draw two whole white pixels... you would do something very similar to drawing just one, only twice.
Pt-Off(1,1
Pt-Off(2,2
Are you still with me? OK, supposing you are too lazy to write all kinds of Pt-Off statements and want to use a loop and a list, you would replace the numbers with elements of the list and loop through these elements.
{1,1,2,2,3,3,4,4,5,5->L1
For(X,1,10,2
Pt-Off(L1(X),L1(X+1
End
Quote: But I know you cant recall a certain part of a list. Um, you can recall every element of a list. |

| With everything you stored to list 1 how would you recall only 2,2 for instance? |

Getting the Nth element of a list:
L1(N
Getting the Nth + 1 element from a list:
L1(N+1
If you want to look through the list and see which element the number 2 is stored to:
For(X,1,Dim(L1
If 2=L1(X:X->Y
End
Y now contains the last element that holds the number 2, with some little modifications you can use this to search for number sequences, every element containing a certain value, etc. |

On your code arcane:
Wouldn't that pick the last number 2 is stored to? |

the code you posted a while ago should be changed to this :
Code:
{1,1,2,2,3,3,4,4,5,5->L1
For(X,1,dim(L1),2
Pt-Off(L1(X),L1(X+1
End

You might want to use lines for that. |
