I noticed while doing some variables in a image processing function that:

imgDataEnd as integer = Get Memblock Size(1) - 4

compiles but will return nothing or 0 rather, however:

imgDataEnd as integer
imgDataEnd = Get Memblock Size(1) - 4

Works just fine.

Would this be considered a bug? What does DBPro define something as when I set a value without declaration? Is it better to declare or let DBPro handle it. I'm inclined to do so either way, but I'm very curious. It would seem rather cumbersome for the system to always be changing a variable dynamically if it changed value beyond a specific type. While I'm at it, when I declare a boolean will that boolean use one byte or does it share bytes with other booleans in the program? Sorry for all the questions but memory optimization is important to me.
