a$: sexp

All lower case letters in a$ are converted to upper case.

This also happens to characters containing umlauts.

Example:

    a$=" test"
    b$=UPPER$(a$)+UPPER$("ware")
    PRINT UPPER$("Gfa basic 3");b$

--> On the screen 'GFA BASIC 3 TESTWARE' appears.

Memo: Umlaut conversion table is as follows:
      Before: üéäàåçæöñãõøœĳ
      After:  ÜÉÄÀÅÇÆÖÑÃÕØŒĲ
