TOLOWER, TOUPPER, TOASCII
Synopsis
Description
The toupper() function converts its lower case alphabetic argument to upper case, the tolower()
routine performs the reverse conversion and the toascii() macro returns a result that is guaranteed
in the range 0-0177. The functions toupper() and tolower() return their arguments if it is not an
alphabetic character.
