lowercase limit

Hi,

is there a way to limit to lowercase letters in inkey function

without editing the bitmap font itself?

Thanks.

Code:

---

string inkey_str;

function inkey_func
{
inkey(inkey_str);
}

function main
{
//code
while(1)
{
str_lwr(inky_str);
wait(1);
}

---

Thanks flits, that´s the function i was looking for
