For agents registered as V40 and earlier:
ArgListattributes (integer and string) are each contained in a single command-line argument.
ArgListattributes (vector, keylist, and association) are contained in one or more command-line arguments.
If a vector or association attribute contains N components, it is represented by N+1 command-line arguments. The first command-line argument is N, and the remaining N arguments correspond to the N components. (See "ArgList" on page 171.)
