[AccessD] Global Variable

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
