I need som help with this, i have 3 variables, they all can have a value between 0 and 1 (as example show), any bether/smarter way to check this? i need to be able to use diffrent commands depending on what the %var is set to..
if (%var1 == 1) || (%var2 == 1) || (%var3 == 0) { do stuff }
if (%var1 == 1) || (%var2 == 0) || (%var3 == 1) { do other stuff }
if (%var1 == 0) || (%var2 == 1) || (%var3 == 1) { do other stuff }
if (%var1 == 0) || (%var2 == 1) || (%var3 == 1) { do stuff }
if (%var1 == 1) || (%var2 == 1) || (%var3 == 0) { do other stuff }
if (%var1 == 1) || (%var2 == 0) || (%var3 == 1) { do other stuff }
if (%var1 == 1) || (%var2 == 0) || (%var3 == 1) { do stuff }
if (%var1 == 1) || (%var2 == 0) || (%var3 == 0) { do other stuff }
if (%var1 == 0) || (%var2 == 0) || (%var3 == 1) { do other stuff }
I hope you understand. Thnx
if ($me != tired) { return } | else { echo -a Get a pot of coffee now $+($me,.) }

To really help you I'd want to know what "stuff" you want to do.

elseif/else-constructs and/or condition-nesting might help... it really depends on what you're after, and on whether some of the various commands are identical or related, and so on.
So far, as you have three instances of "1-0-1" and two instances of "1-1-0" and of "0-1-1", you could merge their respective commands under one condition each, saving 4 lines. Of course only as long as you don't change the variables' values in the commands itself.

You could us a bitwise operation:
var %bitvar = $calc(%var1 + %var2 * 2 + %var3 * 4)
if (%bitvar == 0) { dostuff with all vars = 0 }
elseif (%bitvar == 1) { do stuff with var1 = 1, var2-3 = 0 }
elseif (%bitvar == 2) { do stuff with var2 = 1, var1&3 = 0 }
elseif (%bitvar == 3) { do stuff with var1-2 = 1, var3 = 0 }
elseif (%bitvar == 4) { do stuff with var3 = 1, var1-2 = 0 }
elseif (%bitvar == 5) { do stuff with var1&3 = 1, var2 = 0 }
elseif (%bitvar == 6) { do stuff with var2&3 = 1, var1 = 0 }
elseif (%bitvar == 7) { do stuff with all vars = 1 }That is if the vars are only 0's or 1's and don't change through your coding ....

You could shorten the code in you sig: if ($me == tired) { echo -a Get a pot of coffee now $me $+ . }

I think sparta wants to "return" when not tired, but to get a cup of coffee when he's tired. That sig is served as a satire if you get the drill. :P If the reduced size of the code is concerned, using $iif will shorten it by about 15 bytes. $iif($me != tired,return,echo -a Get a pot of coffee now $me $+ .)

Return by itself in that seems slightly odd. I might have added an extra "command" in there...
if ($me != tired) { Run 10 miles | return } | else { echo -a Get a pot of coffee now $+($me,.) }
Run 10 miles could easily be changed to anything that might make you tired. In other words, if you aren't tired, go get tired and then return for your pot of coffee. If you're already tired, just get the pot of coffee.

Speaking of running, I've attempted to run 10 miles but failed. The longest miles I can run for thus far is five miles. I'm gonna keep training my body and build up my endurance to increase my mileage eventually.  Excuse me for hijacking the thread for a general talk. :P @Froggie, without the else, usually the first if condition needs to be added with a return or halt.
