LSL Alternate Editors lists a number of alternate worlds that work much like the world shown by the Second Life client, including the world of the binary-code-only LSL-Editor for Windows in particular.

In this article we blog differences found between the Second Life implementation of the Linden Scripting Language (LSL) and the LSL-Editor implementation.

By definition, differences found are merely issues, not definitely bugs, until we understand them. Different results seen with a test case are bugs in the implementations or in the specifications. The differences are bugs in the implementations if the specifications say what the implementation should do in the test case, differences are bugs in the specifications if the the specifications don't mention the test case, differences are broken by design if the specification lets the implementation behave indeterminately.

Cast of Cast Syntax

I tested ... offline using LSLEditor 2.15 and got the results I documented ...

Q1. ... Do LSLEditor 2.15 and Second Life 2007-09-12 disagree?

A1a. I checked it in-world and yes, ...

A1b. I checked again with LSLEditor and they really disagree on these results. And it's not the only difference.

This term ie. worked correctly in LSLEditor:
float number;
string char = (string)(integer)float;

which didnt compile in-world and needed be changed to
float number;
string char = (string)((integer)float);

which in LSLEditor worked correctly, too.

Separate Words Results Involving llParseString2List etc.

I tested Separate Words offline using LSLEditor 2.15 and got the results I documented ...

Q1. Are the results I got not the results that everyone gets in world?? Do LSLEditor 2.15 and Second Life 2007-09-12 disagree?

A1a. I checked it in-world and yes, ...
