7.  What is the importance of DFTNAME(rpg_name)?

ü  The name for the compiled module/program is taken from the name specified in the DFTNAME keyword of the control specification.

ü  If the module name/program name is not specified on the control specification, and the source member is from a database file, the member name, specified by the SRCMBR parameter, is used as the module name/program name. If the source is not from a database file then the module name defaults to RPGMOD.
