You can use goto command to jump from one point to another in a script.
Goto's aren't used very much.
alias channels { var %i , %chans :nexti inc %i if (%i > $chan(0)) { return %chans } var %chans = %chans $chan(%i) goto nexti }
Sometimes you may wish to use goto not in connection with 'loops', an example of which is below:
alias Eat {
if ($istok(Apples Pears Nothing,$1,32)) goto $1
echo -at *** You don't fancy anything to eat? I don't know what $1 is.
return
:Apples
echo -at *** You just ate an apple!
return
:Pears
echo -at *** You just ate a pear!
return
:Nothing
echo -at *** Not hungry? You haven't eaten anything.
}
