RPGspUpper Function

Returns the specified character string converted to uppercase.

Syntax

RPGspUpper(character string)

Remarks

RPGspUpper is often used when comparing user name or password strings.

If the string being passed to RPGspUpper contains no lowercase characters, the returned string will be identical to the passed string:

RPGspUpper('hello world') returns 'HELLO WORLD'.

RPGspUpper('Hello World') returns 'HELLO WORLD'.

RPGspUpper('HELLO WORLD') returns 'HELLO WORLD'.

Example

The following is an example of an IF statement that uses RPGspUppper to make the password comparison case-insensitive:

     C                   If        RPGspUpper(RPGspIn('PWD')) = RPGspUpper(PASS)
