    it should be i (lower case letter) not the number 1. variables must always start use a letter up front. I try to avoid letter I and 1 and O and 0 just for that reason. best to avoid confusion is your can

    An alternative to not using certain characters in variable names would be to find a better programming font to help distinguish those characters. It looks like OP is using Courier New, which -- despite being the default on many Windows programs -- is a fairly bad programming font. Nearly no difference between 1 and l and no slashed/dotted zero, among other issues. Consolas is barely any better and still has the same issue with the former, with the added issue of 8 and & being easier to confuse.

    I'm insane and prefer the Proggy family of fonts (specifically Crisp) for personal use, but I am partial to some of the larger, rounder fonts for general use. Source Code Pro and Ubuntu Mono are both great free options.

    If you don't mind the non-monospace, Comic Sans is optimized for having characters that are easily distinguishable.

    syntax highlighting can help tell you what type of keyboard key you pressed such as 1 and 0 being red for Constants and I and O being blue for Variables and Yellow for Local Variables
    though you can change the colors in the preferences

    I never thought I’d see you post anything more useful than your “How to PM a user” guide, but here we are.

    Sorry, did I say “useful”?
    I meant “useless”.
