uppercase wrong changesmall letter into smal in field: code

Jarek

problem is with change of polish letter, or small letter into large, only in field of data type: code
any other data fields : ok!

when you wright Ś in field (for example login:) change on U"umlaut",and in few cases it does not change small letter into large letters (but have to)!?
(function uppercase )

client 3,7A or B nativ
base is 20MB never backed up by navision (always by *.fdb)
(we need migrate this base to 4.0)

we check all possibilities (we think)
debugger/(profiler after opening backup on sql client)
Collation
C/ALL globalls
Regionall settings on computer/server
we removed all codeunits and past from clear cronus 3,7
we check fin.stx

every settings was ok!
any other bases working ok!?

but not this one?!

pls.help
what it could be ?

have you tried to do the change via intermediate variable of text type:

TextVar := CodeTypeField;
TextVar := UPPERCASE(TextVar);
CodeTypeField := TextVar;
