Does 0 memory address on AV mean anything?

Hello,

A user got an Access Violation with the following message:

Access violation at address 00000000. Read of address 00000000.

He couldn't tell me exactly what he was doing at the time, and what he did that led up to the AV. So there's little (or nothing) I can do to troubleshoot this.

However, I find it interesting that the address was 00000000 and am wondering if that's indicative of anything in particular.

Any help would be appreciated.

Possibly you are accessing properties of a form that hasn't been created yet.  Just a SWA Guess.

00000000 is a nil pointer. As roknjohn suggested, possibly a form, but could be any class really, or a dynamic array  that hasn't been initialised, or a record pointer not initialised, or anything. Not much information to go on.
