Hello Rick,
I assume that you want the / and dot symbols to be optional if you want it
to be able to match MSFT. So:
^[A-Z][A-Z]*[\/\.]?
Note: I cannot recall if the / is a special symbol and needs to be escaped
but it doesn't hurt. If you do not escape the dot that is a regex symbol
for any character if memory serves - which it may not.
I used this simulator to test the above using POSIX.

Hi Travis:
I created 2 textboxes and enter the expression in one and the test string in
the other.
Not having much luck so far.
This should work from my megar understanding but fails:
^[A-Z][A-Z]*/.?
Test string:
MSFT.
This fails.
Do you see anything?

Yes asterisk is used for any number of letters.
I believe you will need to escape the period and hyphen as they both have
other meanings in regex as well.
If it can be either/or you would want them inside of brackets also.
It may be helpful to find a regex simulator or write something up quick you
can just run to see what it does like make an app that pops up a message box
of the results of your match, then edit and quick rerun it until you get
what you want.

Hi: I want to edit a ticker symbol in a string all caps.
First position must be letter
Followed by more cap letters, perhaps a dash or period then at least one
more letter.
I have this as a starter does it look even remotely correct?
^[A-Z][A-Z]/-?/.?[A-Z]
Should there be a star in the second factor to indicate there can be any
number of capital letters after the first?
Now I am remembering why I didnt use them a few years ago but I hope I can
learn this time
Thanks Rick USA
