$DESCRIPTION$

     ISUPPER() is a character function that determines whether the first
     character of a string is uppercase.  It is the inverse of ISLOWER().
     Both ISUPPER() and ISLOWER() relate to the UPPER() and LOWER() functions
     which actually convert uppercase characters to lowercase, and vice
     versa.

$EXAMPLES$

       These examples illustrate ISUPPER() applied to various values:

	? ISUPPER("AbCdE")         // Result: .T.
	? ISUPPER("aBCdE")         // Result: .F.
	? ISUPPER("$abcd")         // Result: .F.
	? ISUPPER("8ABCD")         // Result: .F.


$LANG_RU$

          ISUPPER():

       ? ISUPPER("AbCdE")        // : .T.
       ? ISUPPER("aBCdE")        // : .F.
       ? ISUPPER("$abcd")        // : .F.
       ? ISUPPER("8ABCD")        // : .F.
