A question regarding the syntax how to call a function

For some functions, for example, GetFileName, I need to call it like ${GetFileName}. But for other functions, for example, CopyFiles, I can simply call it like CopyFiles. Why'd we have such a difference in calling a function? Thanks.

It's a defined constant. It's a hack to make it like a function, but really it's just inserting !insertmacro GetFileName ... (i.e. !define GetFileName `!insertmacro GetFileName`). Look in the include files.

Edit: In fact that's another reason I've been working on the NSIS assembler which has C-like syntax for built in functions, user functions and macros (see sticky topic).

So GetFileName is just a macro. Then it makes sense. Thanks for your explaination!
