[AccessD] Global Variable

LOL, I am not attempting to scare the life out of him.  I simply said "don't
get carried away with them".

Hi Charlotte and John

But Joe asked about one (1) global. No reason to scare the life of him.

Now, Gustav, you know there are no guarantees for "nice" code, regardless.
It's just easier to write bad code if you lard it with globals, which is why
it is frowned upon by so many of us who prefer to avoid shooting ourselves
in the foot.

Hi John

You may like or prefer or need, or not, a global variable - that's up to
everyone to decide for him/herself - but they are not "bad practice", not
even in general. You may write clumsy code using globals, but not using them
gives no guarantee for nice code.

To dimension a global variable just go to the header of any module and type
in 

Global MyVar as SomeVarType

That's all there is to it, you can now reference the variable from any code
in the project.  Don't get carried away with them, they are considered bad
practice in general.

Hi All,

I am using a code example, from Microsoft, that allows me to print a
constant number of lines on a report. The code example uses a variable that
is defined as Global. "Global TotCount As Integer"

What's the deal with Global? I can't find it defined anywhere.

TIA!
JR
