How to get the number of args in PL/SQL program ?

In one of our PL/SQL programs we do not know in advance how many arguments will be given upon invocation. The arguments can be retrieved by means of the variables &1, &2, etc, but we do not know the actual number of arguments given to this program.

Question:

Is there a way to figure out what the total number of arguments given to a PL/SQL program is ? In other words is there an equivalent in PL/SQL with the argc in a C program ?

Thanx in advance,
