You can enter several different combinations of these operands. The system interprets the operands that you enter according to the following rules:

• When you enter a single number and no other operands, the system assumes that you are accepting the default value of the asterisk (*) and that the number is a value for the count_2 operand.
• When you enter two numbers and no other operands, the system assumes that they are line_number_1 and count_2.
• When you enter two operands and the first is a number and the second begins with a character that is not a number, the system assumes that they are line_number_1 and string_1.
• When you enter three operands and they are all numbers, the system assumes that they are line_number_1, line_number_2, and count_2.
• When you enter three operands and the first two are numbers, but the last begins with a character that is not a number, the system assumes that they are line_number_1, line_number_2, and string_1.
