in thread strange constants.pm warning

Okay, misunderstanding. I thought this happens in your code but it is actually a line from the import() sub of constant.

} else { # Catch-all - what did I miss? If you get this err +or, # please let me know what your constant's name was +. # Write to <rootbeer@redcat.com>. Thanks! warnings::warn("Constant name '$name' has unknown +problems"); }

Your example works here. Perhaps some non-printable characters have sneaked in to your text file or there is a clash (other module or within your code) that uses the same constant? What happens if you change DB_ERROR to MY_DB_ERROR? No better ideas ATM, sorry.

    Your suggestion of the potential of unprintables was very astute- I removed the line and carefuly re-typed it. Same warning.

    I noticed there were 2 constants defined. I moved the 2nd to the top , and now THAT one throws the warning , but the other is fine. So whichever is first throws a warning!

    This makes me wonder- the author doesn't declare:

    use constant;
    above these pragmas. maybe that would fix this? I don't see that in the Metacpan but perhaps they're incomplete examples?

    APPRECIATE all the kind advice guys- I'll wait for the admin to get my module updated and pray for better results :)
