Constants in MQL4

[[Deleted]]

Just a quick question Is there a way of defining a constant? What I mean is defining something like int a = 5; and defining it in such a way that it cannot be altered or if an attempt was made to alter it an error would be generated.

Use #define instruction. Constant declaration

Hi Rosh - thanks that works. I didn't think that method would generate an error if an attempt was made to alter its value but I just tried it out and if you try to alter its value the code won't compile so that is fine. Thanks.
