¿Rodrigo, tu hablar español? Do you speak spanish? :)

It is not really "base 36" because the number system does not increase in units of 36 as like binary is base 2, octal is base 8, hex is base 16, etc. (I mean to say that ASCII is still in only decimal or hex, etc....) Maybe you mean the difference of +30 for numeric characters...and different for A-Z? It is easy to compute in ASM.

It is helpful to print an ASCII chart in order to better understand the format and numeric listing of chars/control chars.

Please be specific ok? And search the forum FIRST please as mentioned by Jose and Andy...thanks.
