Function Upper() Foundation
Converts lower case letters in a character string to upper case.
Upper( <cString> ) --> cUpperCase
The return value of Upper() is a copy of <cString> in which all lower case letters are replaced with upper case letters.
The character function Upper() converts all lower case letters in a character string to upper case. It is the reverse of the function Lower() which converts character strings to lower case.
The letters "a" to "z" are converted by Upper() to "A" to "Z". To convert language-specific special characters like "ä", "ö" and "ü" to upper case letters, the appropriate collation table must be selected.
