The name of the main entry point for the executable program, which must be specified either as class-name::method-name, or just as method-name. For example, ILMAIN"classA::methodB" or ILMAIN"methodB". The first format can be used to distinguish between multiple methods with the same name in different classes.
For procedural managed COBOL, the main entry point is denoted by the Procedure Division Using clause, and the name specified in the ILMAIN directive is the program name.
This parameter cannot be zero-length.
