Script:Generating CREATE USER DDL Statements

Title: Generating CREATE USER DDL Statements

Author:Ted Martin, a database administrator in Ottawa, Ontario, Canada.

These scripts will generate SQL DDL statements related to the creation of user accounts. The types of statements generated
are as follows:

1. CREATE USER and ALTER USER...QUOTA x ON [tabspace] (GENUSER.SQL)

2. CREATE role (GENROLE.SQL)

3. GRANT [role|priv] TO user (GRANTPRIV.SQL)

All three scripts ask for execution parameters. If you leave such a parameter blank, the script will generate for all. The
exception is the prompt for the output filename.
