fun with if and switch
Posted: Thu Aug 21, 2008 3:55 pm
If is a simple function that if the condition is true it runs the first function otherwise it runs the second function.
(if cond a b)
Now you can have nested ifs (ifs inside of ifs) A common thing to see is a if as the b function. An easier way to do that is with switch.
A switch is just a condensed form of nested ifs. If put in the if form it would look like this
The equivalent switch code would be
(if cond a b)

Code: Select all
(if cond1
a1
(if cond2
a2
(if cond3
a3
...
(if condN
aN
default
)
...
)
)
)Code: Select all
(switch
cond1 a1
cond2 a2
cond3 a3
...
cond4 a4
default
)
