Issue about output of "To upper case"

[hrongfu]

If the input of "to upper case" is "\C0\00a", then the output will be "?Aa"

The easiest way to answer that question is to just try it out yourself.

And the answer is no.  It will be \C0\00A  since there is no "upper case" version of the characters C0 and 00 hex.

I am not sure what to make of your post. Is is a question, a comment, or a bug report???

If your string controls/indicators are set to \-codes and you are getting "?Aa", something is wrong. What is your LabVIEW version? Can you attach an example that shows the problem?

The normal and expected behavior is as follows, and that's what I see using LabVIEW.

Assuming that your "\C0\00a" string is actually in \-codes display, we have 3 characters:

1. \C0 is already uppercase, so it won't do anything to it
2. \00 is not a printable character, so it won't change
3. a will chage to uppercase A

Conversely, a "to lower case" would turn your string into "\E0\00a" (in \-code display)

It is a bug report.

And \C0\00a" is a '\' code dispaly, also "?Aa".

 I have tested it on labview 7.1

My Vi is attached

Thanks for the clarification. I no longer have access to 7.1 to test this, but e.g. in 8.2 everything works just fine.

'Seems it got fixed in newer versions.

I still have 6.1. Worked fine at that time.

Sorry hrongfu
I have tested your vi with LabVIEW 7.1. No bug !!!
No idea about what's wrong with your computer. Something corrupted in your setup ?
