String variables are added by NVSE 4. A string is simply some combination of text characters and exists widely in the vanilla game. A string variable allows you to store a string in a similar way to any other variable, and a wide range of functions allow powerful capabilities for them. | String variables are added by NVSE 4.

To appreciate the full range of possibilites available, a [[Tutorial: String Variables|tutorial]] is available. | ||

The [[ToString|ToString (shorthand: '$')]] function converts anything to a string. Vanilla and some old NVSE functions also require this to use a string_var instead of a string literal: | |||
<pre> | |||
Print my_string ; * new NVSE function | |||
MessageEx $my_string ; * An old NVSE function | |||
</pre> | </pre> | ||
If you want to use [[String Formatting]] rather than concatanation (+), you need to use [[Sv_Construct]]: | |||
