1.10.3 Conversion to lower/upper case

This functionality can be used to convert all letters in
a string to a uniform case.
Syntax:
STRING_ERG = TOUPPER
STRING_ERG = TOLOWER
Semantics:
All lower case letters are converted to either upper
case or lower case letters.
Example:
Since user inputs can also be activated on the MMC, it
is possible to achieve uniform representation of text
(i.e. upper case or lower case):
DEF STRING [29] STRG
...
IF "LEARN.CNC" == TOUPPER (STRG) GOTOF LOAD_LEARN
