Dennis,

According to my copy of 'A Guide To SQL Standard (Author: C. J. Date), 4th ed, pp292, section 19.4"

CHARACTER(n) - fixed length string of exactly n characters (n > 0) VARYING(n) - varying length string of up to n characters (n > 0)

So, I guess it is.

My understanding is that VARCHAR2 is not even a SQL standard, and some databases don't handle VARCHAR very efficiently, so if you are trying to sell a product that can adapt to several databases besides Oracle, you might stick to CHAR.

If your application is COBOL-based, using CHAR simplifies things quite a bit. Especially if you sell your application to many sites that want to use Oracle underneath but don't have an Oracle DBA, at least not initially. Yeah it wastes a bit of disk space.
