What are the different dm_method options

A dm_method object has several attributes that affect how an documentum object behaves:

* launch_async indicates whether a procedure is to run asynchronously or not.
* method_type is used when a program is stored as content for the method. If set to GAWK or dmbasic, it directs the server to add -f in front of the file name and to pass all arguments specified on the DO_METHOD command line to the program.
* method_verb is the command-line name of the program to execute.
* run_as_server indicates if you want a method to run as the server account.
* use_method_content indicates whether the program that you want to run is stored as documentum content in the method object or as an external file.
