The problem with that, LostShadow, is that the number isn't exactly 950 characters.
I use 950 as a base, and most of the time it works fine, but the true limit, if I remember correctly, can be calculated as:
967 - (number of characters in variable name)
So the actual number of characters that you can have in a variable, also depends on the number of characters in the variable name.
Very few people work with variable names that are 17 characters (or more), which is why I normally use the 950.
