how do you convert an ASCII character into a decimal number?

[maplesirop]

If I have an input

Code: [Select]

mov eax, 3
mov ebx, 0
mov ecx, input
mov edx, 10
int 0x80
how do I convert input into a decimal number?

Code: [Select]

mov eax, 3
mov ebx, 0
mov ecx, input
str2int data
mov edx, 10
int 0x80
would this convert ecx into an int decimal?
