Double quotes added to variables

At times, double quotes seem to be added to string variables in Test Complete.  This may be a vbscript issue, I am not sure.  However, I have seen that a variable could end up having its value change like this:

"data"

""data""

"""data"""

The more I keep using it, the more double quotes get added to the value of the variable.  To bypass, I actually started creating copies of the variable since the value was not going to change anyways like so:

Dim data1

Dim data2

Dim data3

data1 = "blah"

data2 = "blah"

data3 = "blah"

This is very wasteful, I know.  But, I can not figure out why these so called phantom double quotes keep injecting themselves into my code.

Any ideas?

Thanks in advance!
