How do I do the mq2 equivalent of variable++ or variable+=1? ATM I have the following:

/declare randomvariable int outer


Sub Event_SomethingorOther
     /varcalc randomvariable ${randomevariable}+1
/return

This gives me an error everytime, not a fatal error, just that ${randomvariable} is not found or something like that.

Did you actually give randomvariable a value anywhere? try

/declare randomvariable int outer 0

yes i have:

/varset randomvariable 0

in sub Main

Here is how I'd do it.

/declare randomvariable int outer 0

Sub Event_SomethingorOther
     /varset randomevariable ${Math.Calc[${randomevariable} + 1].Int}
/return

yes i have:

/varset randomvariable 0

in sub Main

Out of curiosity, why not just have the 0 in the /declare?

Cuz I didn't know that could be done.

Also, I found the problem. Turns out mq2 is not like c++. In c++, you can declare global variables outside a function/subroutine. In mq2, they have to be declared within a sub. I had to move them to sub Main and now it works.
