I seem to have run across a weird quirk in LSL that I'm curious if anyone else has noticed and/or found good work-arounds for. I have an if block in one of my scripts that I needed to put 31 else if's in. On compiling, I got a syntax error, and after commenting out various sections of the code to try to find a mistake, I found instead that the code would compile only as long as I had 18 or fewer else if statements in the if block. I even tried putting the rest of my else if statements in an else if (TRUE) block, to try to make a work-around, and that didn't compile either.

From the LSL Wiki:

Note: Only up to 23 else statements may be in a conditional chain. (a total of 24 conditionals: 1 if and 23 elses) Any more, and a syntax error will occur when the script is saved/compiled. However, a workaround to this is to nest conditionals, or, if that's not possible, split the conditional chain into a series of distinct if statements: at the end of each if(){} block, put a jump or return as the last statement so that the remaining if statements that would have otherwise been "else if" statements are skipped.

It wouldn't surprise me if that "23" was not carved in stone.

Just embed a couple of those else-if statements and you'll be good again.

Thanks, I've got a good workaround working now.
