UPCASE
Converts alphabetic characters to uppercase.
Synopsis
UPCASE(string)
Arguments
| string | An expression that resolves to a string. |
Description
The UPCASE function returns a string of characters with all lowercase letters converted to uppercase. Characters other than lowercase letters are passed through unchanged. If you specify a null string, UPCASE returns a null string.
By default, UPCASE performs case conversion on ANSI Latin-1 letters. To perform case conversion on letters in other character sets, you must set the appropriate locale.
The OCONV function with the “MCU” option is functionally identical to the UPCASE function. To convert uppercase to lowercase, use the DOWNCASE function.
Examples
The following example uses the UPCASE function to convert lowercase letters to uppercase:
MyString = "Caché from InterSystems"
PRINT UPCASE(MyString)
! Returns "CACHÉ FROM INTERSYSTEMS"
