Limiting input

-----------------------------------

How do i limit the input to for example 3 characters without like doing a string and ignoring everything after the 3rd part.

Not sure exactly what you're looking for, but a loop with getch() or Input.KeyDown() would work.

What i am asking is that if for example, i ask for someone's student number. 
I know it is 9 digits, how do I prevent the user from entering over 9 digits?

RE:Limiting input

you ask for the input 1 character at a time (using getch()) and keep a count of how much the user has entered so far.

Use getch () in a for loop, and add the input to a string. This way, you can getch 9 times, and it will automatically end the getting.

Thanks for the reply guys, I really appreciate it.
I have another problem
I need the user to input a name, first and last, but the get statement only gets the info until the space, so the last name is ignored, how do I get the full name in 1 string?

when typing multiple words into a string, you need to put quoteations around them. 

input (Harold Haselhoff) will return 'Harold', while input ("Harold Haselhoff") will return Harold Haselhoff.

Actually, not quite. get only captures input up to the first whitespace in the string that it's trying to capture from. To counter this, you'll need to use:

var foo : string := "";
get foo :*;


the :* following the get statement will make sure that you capture all input that the user provides, even whitespce.

I've always used quotations, but then, I never knew you could do it your way. Oh, well, Turing is behind me. 

But quotations will cancel out the 'no white space' thing.

For reference, you could also make a second variable. might take a bit of extra time but no extra steps are needed in the inputting stage
