What compiler doesn't do syntax checking anymore? One program I use even does it as you type.

But you're right about variables. In my chosen language, things get very fun.

First of all, case is sensitive, so that 'X' is a different variable from 'x'.

But further, it's what's called a "strongly typed" language. Variables are not 'general purpose' but must be defined as to their type - byte, short, long, signed, unsigned, single, double, giant, string, addresses, and complex numbers. There's all sorts of suffix symbols used to denote what type a variable is. Mistyping those has caused me a headache or two.

There's pros and cons to both strong and weak typing method.
