${SYMBOL} and FindWindow strangeness

The following code:
FindWindow ${MIRANDA_HWND} Miranda
gives me this error:
FindWindow expects 2-3 parameters, got 1.

$0 works. Why can't I do like this?

You should use the variables $0-$9 and $R0-$R9, you cannot use your own variable names.

When is it not possible to use own variables?

$0, $1, $2, $3, $4, $5, $6, $7, $8, $9, $R0, $R1, $R2, $R3, $R4, $R5, $R6, $R7, $R8, $R9 are user variables, you should use them for the output of instructions such as FindWindow.

You can use ${SYMBOL} to globally define something, for example:
#define TEST 123
now ${TEST} will be replaced by 123

okay... imo it'd be possible to write cleaner more easily understandable code.. but maybe that's just me

That's right, but it's very diffucult to write such a system for NSIS.

You can define such a global value for nicer names.

For example:
!define HWND $0

Now ${HWND} will be replaced by $0 in the compiler.
