Either &0, or 0&

[Cecil]

In Visual FoxPro we use the & (Ampersand_ symbol to designate a variable as being a macro expansion, so that if a variable represents a command, for example, using something like &RunThis, the placement of that variable will actually run the command it represents.



So, my question is, what does &0 or 0& represent? I can't remember which came first, the 0 or the ampersand. I saw it in some VBA code a few days ago and was curious what its purpose is.

It is a "type-declaration character" and in this case it types it as a Long Integer.

So, is it declared as 0& or &0?

I believe it is a trailing declaration. I use Dim Statements so I'm not real familiar with this method. I also use Option Explicit so the compiler will catch my mistakes.

I use Ampersand Hex all the time when defining static objects for tcp ip packets in vb+.

Like
Packet.InsertBye(&HFF)
Check in Immediate
?&HFF
returns 255

Ive never really used it as ?&123

& But itself like 0&0 will concatenate the two values. See immediate window ?0&0
