can variable names end with a $ or &
 

Can vba variable names end with a $ or &? And if they can, is there
something special about them?

I see rules that state: "The name can't contain a space or any of the
following characters: . ! # $ % & @"

But - here I am looking at at a program that has them...

Thank you.

Those are 'Type' symbols used as shortcuts for typing 'As <datatype'.
They can be used to Dim/declare a variable but won't be needed when
using the variable in code...

Dim sData$ '//string
Dim lLastRow& '//long
Dim n% '//integer
..and so on...

sData = "MyName": lLastRow = 500: n = 0

...uses the variables without the 'Type' symbols. Note that there are
some structs that do not permit using 'Type' symbols, and VB will let
you know when you try using them inappropriately.

Note that some functions also implement the symbols. Some that come to
mind for string functions are...

Mid$()
Left$()
Right$()

Look at pretty much any code I post that manipulates strings. I always
include the $ in the function's name. (Habit from the QB days, plus other
BASICs still require them.)

Yeah.., me too! I got into the habit of using the symbols when defining
vars just for the brevity. I've been posting a lot of replies that use
them just out of habit. I'm thinking if people understand what they
mean then so be it, but if not then it probably doesn't matter anyway
since those would be looking for 'turnkey' solutions they wouldn't
understand in the 1st place<g!
