SQL Create Table Like an existing table

I have an existing permanent SQL-created file. I want to create another
file in the same library that has the same exact structure (fields, keys,
constraints, etc) and am having difficulty doing so. This new file is not a
work or temporary file, it is permanent. I do not want to rename all the
141 fields in the DDL as the 2 files will _always_ have the same structure.

I tried this:

CREATE TABLE JEFF/newfile
LIKE JEFF/oldfile
PRIMARY KEY ( ITNBR ) ,
CONSTRAINT imPrcBkSeqUK UNIQUE (MBGROP , MBSBGP , MBLINE)
NOT VOLATILE
RCDFMT MBRECORD ;

But it balked at the PRIMARY KEY.

So I did this:

CREATE TABLE JEFF/newfile
LIKE JEFF/oldfile
NOT VOLATILE
RCDFMT MBRECORD ;

Which worked, but now I need to get all 15+ constraints in, including
primary key, unique keys, foreign keys, and check. Do I need a separate
ALTER TABLE for each and every one of these? I was hoping to combine them
into 1 ALTER TABLE, but can't seem to determine the syntax.

The actual ideal would be something like:

CREATE TABLE JEFF/newfile
LIKE JEFF/oldfile
WITH CONSTRAINTS
NOT VOLATILE
RCDFMT MBRECORD ;

But I don't see any examples like that anywhere <g>.

Any help appreciated.
