Pointers to variable or structure?

[Sensphere]

Why does this work:

Code: Select all

a.POINT
*b.POINT
a\x  = 0
*b = @a
*b\x = -1
CallDebugger
Debug a\x

Changed the x value of a successfully!

But this one will not:

Code: Select all

a.l
*b.l
a  = 0
*b = @a
*b = -1
CallDebugger
Debug a\x

Isn't it possible to get a pointer to a long variable (or anything other than a structure)???

In the second is a bug: it should call debug a not a\x

Try this:

Code: Select all

a.l
*b.long
a  = 0
*b = @a
*b\l = -1

Debug a

Ok, this is working - but isn't it a bit weird - because a pointer to a long value shouldn't be a structure?!

PureBasic's pointer notation is simpler than e.g. C, so there is no way to access both the pointer and the data within for simple data types without making it point to a structure which contains the simple data type.

Or use Peek and Poke :)
