Archie:
The Value is only a 65, so it can't be reading a custom length string. Any custom length string will return at least 8 characters such as 01000000, which represents the length in hex format, then there will be the number of hex values representing the characters.

Are you completely sure the tag you are reading is a custom length string?

Archie:
I think I may be leading you down the wrong path because I may be misunderstanding the goal.

If you look at the string in RSLogix, do you see '65' ?

JasonT:
The tag I am reading is only part of the string. The string is WX,OK,A,W5G18023$r$1D14198085 and the .DATA[6] is the tag that I am reading which is the character "A" in the string.
Since that is the only information I need from that string, that is the tag I used

Archie:
Ok. So I completely misunderstood and went down the totally wrong path. This will be much simpler.

Where you had this code:

Label1.Text=ExtractString(BasicLabel1.Text)

Change it to this:

Label1.Text=chr(BasicLabel1.Text)
