DB funtions pass by value. Is there a way to pass a pointer, then dereference it? Can this be achieved through memblock functions, and if so, how? If not, is there a way to return more than 1 variable from a function without using some type of array? (if that's even possible)

I'm getting sick of gosubs...

I'm sure this would be an easy question to answer for somebody who uses the enhancement pack... *sigh*

In C, you tackel the problem of only returning 1 variable from a function with pointers.

Example of problem:


The screen will display that x=5 and y=10, not y=0

This is tackled by passing the "label" in RAM of the variables. In the function, you go to where the label is pointing and change that place in RAM directly, instead of creating temporary variables to return a value.

This will actually report that x=5 and that y=0!

Any way to do this in DB?

No, only in DBPro. Another good reason to upgrade

Pointers and References were one of the things that really confused me about C++ hehe.
