Some commands take a format string as a parameter. Format strings are actually a collection of arguments consisting of a string followed by zero to twenty variables. The string specifies how the command should use the rest of the arguments to construct a new string. Within the format string, percent signs are used to indicate special characters. The number of format specifiers in the string must match exactly the provided arguments | Some commands take a format string as a parameter.

==NVSE Alternative To Formatting== | |||
As an alternative to string formatting, with NVSE functions such as [[Print]], you can use string concatanation and the [[ToString|ToString($)]] function. | |||
<pre> | |||
int iVal | |||
ref rActor | |||
PrintToConsole "Value of iVal is %g and name of rActor is %n" iVal, rActor | |||
; can instead be written as: | |||
Print "Value of iVal is " + $iVal + " and name of rActor is " + $rActor | |||
</pre> | |||
