see -help ifcmd-: I think you are looking for -if else-. If you have
three conditions it should look something like this:

if expression1 {
    do something
}
else if expression2 {
    do something else
}
else if expression3{
    do something weird
}

(This does nothing when expression1, expression2, and expression3 are
false)

Also see: Kantor, David and Nick Cox (2005) Depending on conditions: a
tutorial on the cond() function, The Stata Journal, 5(3): 413-420.
