Max string size

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

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?

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

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

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

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

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

erm..

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

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


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

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

nvm i found an easier way:
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
