I think this would be useful.

Why don't you make all elements lowercase and then use findmapelement(map(), lcase(string))?

Well yes, that would be one solution. But I think #PB_String_NoCase would be easier to code, and would bring that command in line with FindString().

but the problem ist:
Code: Select all
NewMap Test.i()
Test("Case") = 1
Test("casE") = 2
Debug Test("Case")
Debug Test("casE")
FindMapElement(Test(), "case", #PB_String_NoCase)
which element is now to be found?
Case ?
casE ?
or none Element, because it is not unique ?

That would be for Fred/Freak to decide.
I would suggest the first element that is found. If the programmer is using #PB_String_NoCase he should be aware if there could be multiple matching elements in the map and it's a risk he can choose to take.

A #PB_String_NoCase would also slow down the hash map a lot, in fact it might be almost as fast to just use a list I suspect.
