Running the program

Now run the program. For each of the nine columns, the program asks for the numbers of the rows in which you want dots to appear. Enter the row numbers one at a time, pressing the Enter key after each one. When you have entered all the numbers for a column or when you want no dots in a column, press Enter without a number. Remember that the vertical lines in the grid are the even-numbered columns.

To see the program produce the Mercury symbol, run the program and follow these instructions:

1.When the screen message asks what rows have dots in column 1, press Enter to indicate that no dots go in that column.

2.For column 2 (the vertical line) press 7, Enter, 5, and Enter again to indicate that you want dots in rows 7 and 5. Then press Enter alone to indicate that no more dots go in column 2.

3.For column 3 press 8, 6, 4, and 2, and Enter after each of them. Press Enter to finish with column 3 and go on to column 4. (The rest of the directions assume that you know to press Enter after each number and one extra time to end the entries for each column.)

4.For column 4 enter 6, 4, and 2.5.For column 5 enter 6, 4, 3, 2, and 1.6.For column 6 enter 6, 4, and 2.7.For column 7 enter 8, 6, 4, and 2.8.For column 8 enter 7 and 5.9.For column 9 press Enter only.

Now wait a moment for your computer to calculate the dot patterns and your printer to print the new character in two different typestyles and
