Re^2: How to eliminate warning message on hash value?

If you use BerkeleyDB and you use c_get / db_put / etc., you get a '' on success and a 'Err message' on failure. So you would have to '!' the function call. Only for BerkeleyDB, I define my TRUE/FALSE in reverse. But as you pointed out, I should have done as you proposed and it would have been a true perl function call, only it still has to return to the application a '' for success.

Thank you

Please don't define `TRUE` to be something false!!! Call it `SUCCESS` or something. And if it does return `''` as you say, then you'll get a warning for using `==` since `''` is not a number. Use `eq` to do a string comparison.	[reply] [d/l] [select]
