In my game i have :

code:

get answer

and answer is an int, and if the user enters something other than an int, it messes up the program, and gives me an error, since its the wrong type, so i want to make it error proof, and keep asking the question, and then if what the user types in is any int, then it will continue the game.
So how would i make the program check if the input is any int

strintok()
strint()

there may also be a tutorial on error proofing

im not trying to switch from a string to an int or anything.. i jus want to chek if the input was any int number.. and if it was.. then continue on

[Bacchus]

code:

var errorproof:string var num:int loop    cls    put "Please enter an Integer"    get errorproof    if strintok(errorproof) then       num:=strint(errorproof)       exit    end if    put "That is not an Integer!"    delay(500) end loop put "That IS an Integer!"

ooo.. ok i get it now.. yea it works great.. thanx!

Another thing i want to error proof is.. i ask the user to enter their name.. and i want to make it loop the question if they enter more than 15 characters.. so how would i make a loop for that.. and it exits when the user inputs 15 characters or less?

code:

var name : string loop     put "Enter a name (Less then or equal to 15 chars)"     get name     if length (name) >= 16 then         put "I sad less then or eqaul to 15!"         delay (500)         cls     else         exit when name = name     end if end loop put "Your name is ", name

hey .. thnx Flickerator.. worked great!

Flik: you don't need that exit when name = name part. Simply typing exit is good enough.
Also, it would be a good idea to use get : *. Try running flik's code, and inputing "ABCDEFG HIJKLMNO". That string is >= 16, but it tells you you're name is ABCDEFG because get stops at spaces. get : * only stops at enter, however, so it will take the whole line of input into the variable.
Also, if you don't have get : *, it can mess up the next get in your program. Without the : *, try inputting "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA". All the A's before the space will be put into the name variable. Name is greater than 16, so it tells you that it is and restarts the loop. Then it trys to get input again, but there's still stuff in the keyboard buffer. So it takes that stuff, and then puts it into name. name is once again greater than 16, so it tells you so, AGAIN!

Wow I didn't know about thatr keyboard buffer part, good to know. I also didn't know about just exit so thanks ^^;

yea i used the :* after the get.. helps also wit the error proofing. Thanx
