problems with getch

[hey_joe42]

i have a problem with getch it only seems to work with strings of length 1
well what if i wanted to getch something at a certian length like four, like i wanted the user to type like 4 digits
like okay here is what the user in their heads are going to type
abcdef
k but the variable can only hold 4 characters, so when the user gets to d of its input it stops them and they don't have to hit enter
how can you do this

[Dan]

code:

var name:string (4) put "put in 4 letters" get name:4 put name

this will input as may letters as they type but will only store 4 of them in the varible name (the 1st 4).

[Tony]

it would be the same as

code:

get text put text(1..4)

the question as I can see is getting 4 characters without pressing enter. The answer - forloop!

code:

var text:string := "" var c:string(1) for i:1..4 getch(c) put c.. text += c end for put "" put text

there is another way to do it that I am currently using for highscores (only 3 character initials)

code:

var pnamec1 : string (1) var pnamec2 : string (1) var pnamec3 : string (1) var pname : string (3) put "Please enter player name:".. getch (pnamec1) put pnamec1 .. getch (pnamec2) put pnamec2 .. getch (pnamec3) put pnamec3 pname := pnamec1 + pnamec2 + pnamec3

It's sorta inefficient but if it's only for 4 characters who cares

[Tony]

you see... the forloop does the same thing, but you can change how many characters you want

thx for sharing your ideas though

now whatever well i was working on my program
i was switching everything to this cuz it just easy it not the sasme but there are no errors except i ran into this problem trying to change get product:* to get product:10 but what do i do if it two words?

[azndragon]

get product:10 will only accept the first 10 letters entered, or more accurately, only 10 ASCII values, which include spaces. If you want it to correctly accept input for 2 words, you have to type in 2 words, 1 with 5 letters, the other with 4 letters.

5 letters + 1 space + 4 letters = 10 letters total collected by Turing.

[Tony]

you can still employ a getch inside a forloop set to 10. It will input space as a character.
