I know the max number of if-else is 24 (1 if and 23 elses), but what about the max number of straight ifs without elses (eg, if(this){that;} if(who){why;} etc)? Empirically, the max number appears to be 42. That's my assumption based on me getting a syntax error after the first equals sign in the 43rd if statement. Does anybody know for sure?

It's a little more complicated then that. It has to do with the number of entries in the compilers stack. Globals and variables in the function/event contribute to the stack. I've not seen the 42 limit before.

In my case, the variable being tested is the same every time (eg, if(myVar==1){ doThis();}if(myVar==2){doThat();} etc). I did so to get around the 24 if/else limit. Is this bad practice? I need to test against 70 possibilities. My understanding from the wiki is to reach the 23 limit, then use a jump. Sounds clunky, is there a better way?

Scratch that, my bad, the script is choking on a 'special' character from the Latin-1 character set. Which is very depressing, since the same script is happily reading such characters in an hhtp_response and outputting them to the chat window with no problems at all  |

A lot of if statements without else will make the script very slow. It depends on what you want to do. I saw some big scripts with a lot of if that can be replaced by just one, or none  . This is a silly example, but I saw stuff like: if (number == 1) { llSay(0,"1"  ; } if (number == 2) { llSay(0,"2" ; } ----- So analyze the case and check if you really need all those "If" |
