how do you make it so that if a person puts in more than 256 characters or whatever the limit is it doesn't crash? can you make it so theres no limit?

code:
var str : string
put "enter the string"
get str : 6
put str


this for example will only get the first 6 characters in the string

Post subject:  this is how i do it
var text : string (20)

get text : 20

put text

This limits both the variable and the text you can enter. Right now it is 20 but you can change it to the 250 limit

hey nate:P (to both) they dont work.....if you put in a number larger than 255 its an error

mephi, are you trying to exceed the 255 cap or make it so that the user doesn't enter into the 255 cap?

Post subject:  both
well exceed mainly, but i guess just limiting is ok too....thx....as long as it duznt crash (my comp teachers really stingy, he keeps tryin to crash our programs ne way possible)

Post subject:  erm..
code:
var x :string
get x : 8
put x, "!"


how come if its less than 8 the ! goes on a different line? or is this just me?

I belive this issue was already addressed by the use of getch() in a loop

code:

var c:string(1) %for getch
var text:string := "" %store text here
var counter:int := 0 %counter

put "enter your string, 255 max"

loop
getch(c)
if c=chr(10) then %if enter is pressed
exit
end if
text := text + c
counter += 1

if counter =255 then %your string is already 255 long
put "I said 255 characters max"
exit
end if

end loop

put "your string is : ", text

nvm i found an easier way:
code:
var x : string
get x
if length (x) > 8 then
    x := x (1 .. 8)
end if
put x, "!"

just takes first 8 characters

well you can still type in 300 characters and your program will crash. Using getch will read input 1 key at a time, safeguarding your string variable

have 'get x' allows the user to input 1000s of characters
