Scripting Your World: The Official Guide to Second Life® Scripting

VARIABLES

Variables provide a place to store temporary working values. Variables can be both global and local. Global

variables are available to everything in the script, while local variables are available only to the block they

were defined in. A variable name must start with an ASCII letter or an underscore. Numerals may be part

of a variable name after the first character, and non-ASCII letters, while allowed, are ignored. Thus, valid

declarations include the following:

integer x;

integer y1;

integer _z;

integer thisIs_ALongComplicatedVariable_42;

integer enumerator;

integer _enumerator;

integer énumérateur; // same as numrateur

However, you can not also declare an integer numrateur because LSL ignores the é, and

thus thinks the name has previously been declared in scope; that is, numrateur is the same variable as

énumérateur.

and you'll be fine. Consider the following example:

foo() {

integer bar = 0;

llOwnerSay("bar is "+(string)bar);

integer baz = 0;

llOwnerSay("baz is "+(string)baz);
