Translating with DrWatson… this can take a few seconds the first time.
This is a genuine, complex translation. DrWatson protects commands, error codes, and log output while naturally translating the surrounding text. It’s translated once and saved.

You simply can't do what you want. In databases, NULL means unknown.
As soon as you place any characters into a character variable, it now
has a known value.
Is the reason for trying to put a "NULL" after the data so that you
don't get a load of spaces in reports? Then look at the CLIPPED
function, which will eradicate trailing spaces in variables.
