Stu,

While not as much fun, here's another simple solution to those concerns that retains DEF LCASE's ability to deal with the entire char set:

' ----- BEGIN FB^3 CODE -------

LOCAL FN LCASE$( theStr as str255 )
DEF LCASE(theStr)
END FN = theStr

DIM myStr AS STR255

myStr = "THIS IS A TEST OF THE LOWER CASE FUNCTION: "

PRINT fn LCASE$( myStr )+"""" + fn LCASE$( "ÑÜÅÇÉ" ) + """"'Add strings
