Global, local naming scheme

So there are 3 different ways of saying almost exactly the same thing
Not exactly the same, but they should be !
Then there is another problem that when you declare a global variable and redeclare it locally WSH will complain the variable is already used globally. But it shouldn't, a global variable that is redeclared locally should be local making the global variable inaccessible.
I noticed some always append local variables with "my"... That may be not a bad idea...
Now I need to think out a good naming scheme to overcome these bad programming styles promoted by MS. And it gets worse, you can't declare the type of variable beforehand so you'll easily loose track of what kind of variable you're actually working with. Is it an array or a collection ?
I haven't listed all types as I haven't used them yet... But so far, What you guys think of this ?

Heres a function IsBlank() for dealing with null/empty variables

Some naming suggestions here:

An argument could be made for using the b prefix for Byte and f (flag) for boolean

Why does the IsBlank() function at ss64.com/vb/syntax-null.html have all of the Exit Functions? They are not needed with they way the function is written.

^ Good point, I've stripped them out now.

Code: Select all
Set object = Nothing
variable = Null
variable = Empty

Code: Select all
Dim variable : variable = something
Function myFunc( myVariable )
'My code here
End Function
Code: Select all
' Abbrevations for VBScript : long : short
'
' myObject global scope : glbMyObject : MyObject
' myObject local scope : locMyObject : lMyObject
'
' myObject STRING : strMyObject : sMyObject
' myObject INTEGER : intMyObject : iMyObject
' myObject BOOLEAN : blnMyObject : bMyObject
' myObject ARRAY : arrMyObject : aMyObject
' myObject COLLECTION : colMyObject : cMyObject
' myObject OBJECT : objMyObject : oMyObject
' myObject CLASS : clsMyObject : MyObject
