Sorry, but I'm not completely sure what the problem is.
So, here's the error:

Code: Select all

Illegal function call
*highlights line #17*

here's the QB version:

Code: Select all

MS-DOS QBasic
Version 1.1
Copyright (C) Microsoft Corporation, 1987-1992.

and, here's the code:

Code: Select all

FOR x = 1 TO 36

PSET (x - 1, y - 1), z

And if you would like to know my intentions, I'm trying to make a amateur *air quotes* screen saver.
