Hey there.
I'm trying to solve this problem of "redefining the macro". My english is bad so I will show you the code and I hope you can help me.

PHP код:

#define MACRO1<%0>[%1]     %0[%1]
#define MACRO1<%0>        %0 


I thought about to make multiple macros but I don't know how to separate if the player enter a specific index (or length if he declares the variable) and when he doesn't enter something.
