Hi Jerson,

There is a nice helper for this kind of situation in U++. The macro GLOBAL_VAR (probably undocumented too Smile

). It creates a function returning static variable, so in effect it can be used as global variable accessible wherever you declare the function and BLITZ-safe. The usage is simple, e.g.:

GLOBAL_VAR(int,gvar);
gvar() = 5; //setting
int b = gvar(); //getting

The price is typing the extra two parenthesis, but as global variables are not used very often, it should be not a big trouble.

Best regards,
Honza
