Weird, frustrating problem with integer math. I have a 64 bit integer variable that I am trying to use to scan through a file (file position offset value) that simply will not play nice with 32 bit values. No matter what I do, I just cannot alter it, it will not accept any values other than constants. I tried turning on "Use 64 bit math" in the build setting, to no avail. Is there some kind of conversion I need to do to get it to accept other values?
