"when I place the cursor over the above statement"... this message appears:
"cannot access memory at address 0x0"
I have a character array which when the cursor is above displays the data
within the array.
Question, I am not 'assigning' a memory location, so what/why is Netbeans
unable to access the array?

Asuming that this is during debugging ...
When you place the cursor above a statement the "balloon evaluation" mechanism kicks in
where it picks an expression, either the token directly under the cursor, or
some "expansion" of it and attempts to evaluate it.
So, no-one is assigning anything and the "access" is a read access.
It's likely that you can reproduce the same error with print commands, er
watches and that would directly implicate the debugger engine and/or the compiler
that generates debugging information for it.
Is the error in a "baloon-eval" "tool-tip" window or in a heavier weight error dialog
that has to be explicitly dismissed? |

I was trying to gauge the annoyance factor. The balloon eval window can be "waved away" so
to speak. An error dialog with an OK button is much more of an annoyance.

displays!

"the run"?

Thanks for responding, Kevin
