String with Len 0

[Horst]

Hello

aMessgeraet [nCnt][02] is empty and sLen = 0
cUsername is not empty


IF aMessgeraet [nCnt][02] = cUsername -> false
IF cUsername = aMessgeraet [nCnt][02] -> true

This shoud be a bug ?
i have xsharp (2.18.0.4)

Hi Horst,

It's not a bug in the sense that this is how VO works, too, with the partial equality operator when there's a usual involved.

If you want to test for absolute equality, you need to use the == operator. Or you can turn SetExact(TRUE).

Hi Chris

I know when i compare "Horst " = "Horst" or "Horst" = "Horst " then is the result different, but a empty string ? Thats weird for me.

Hi Horst,

Well, VO is extremely weird at times

I agree, it does not make much sense, but we had to implement it the same way as in VO, otherwise it would certainly break existing (ported to X#) code.

Actually, this was "inherited" from dBase (so from the 80s)
