If I am correct case selection has to do with if statements right?
well thank you to whoever posts an example.

yah..for example

code:

var char : string

put "Enter a letter grade."
get char

case char of:

 label "A"
   put "Good job"
 label "B"
   put "Nice work, your almost there."
 label "C"
   put "That's ok, try harder."
 label "D"
   put "You have to get your act into gear quick."
 label "F"
   put "Your a failure."
 label ""
   put "You entered an invalid grade, try again."
end case

its somethin like this, i forgot the format cuz i haven't used it in a while

that looks like Ti 83+ plus programming

lol, TI 83+ programming is much worse...god it takes so long just to do a stupid quadratic formula program.

no it doesn't... making a quadratic program is easy, making a factoring program takes a long time

case still sucks cuz it's getch. i'd prefer input.keydown myself

case is sorta easier 2 work with

????????????
case = getch?
????????????

I always thought case was an alternate if thingie.

it is an alternate, but _restricted_, if statement syntax.
just a cosmetic feature of the language.

so why is case used if it is more restricted, and therefore, offers less options then if? Does it compile quicker or something? Or is it just more user friendly? (but if/then is very user friendly....I don't see how you can get more simpler by using case....)

why do they have more than one type of operating system? its all about preference

get char

case char of:

label "A"
put "Good job"


that's basically like getch in a sense (but more towards if statements).

it isnt like getch, its a basic language construct altho everything it does can be done using ifs and elsifs (or just ifs and elses for that matter)

they are also very helpful in languages like Java where you don't have any elseif statement... just if and else...

so like you could have (not using java syntax, but the idea...)
code:

if this = a then
  do this
else
  if this = b then
    do this
  else
    if this = c then
      do this
    end if
  end if
end if


or you could just have (not using java syntax, but the idea...)
code:

case this of:
label a:
  do this
label b:
  do this
label c:
  do this
end case


so probably it's in Turing to teach you (because as we all know, turing is just for learning to program Rolling Eyes ) about them, so when you go to learn something like Java, you aren't like wtf is this??
