    ISUNSPECIFIED

    Purpose: Returns 1 if input is an unspecified formal parameter

    Syntax:  ISUNSPECIFIED(a)

              a - Any input

    Returns: An integer, 1 if the input is an unspecified formal, else 0.

    Example:
             utest(x, y)
             {
                val = isunspecified(y);

                return(val);
             }
             
             a = utest(1);
             b = utest(1, 2);
 
             a == 1
             b == 0

    Remarks:
             ISUNSPECIFIED always returns an integer.
