All of the work in this project is my own!  I have not left copies of my code in public folders on university computers. I have not given any of this project to others. I will not give any portion of this project to others taking this class. I realize that the penalty for turning in work that is not my own can range from an "F" in the class to dismissal from Trinity University.

53] Write the line of code that could be entered in the command window to display all of the information about all of the Bald Texas Clients. (Try it and record the solution below) How many clients were displayed?

54] Write a program, called Main.PRG which includes the following code.

Turn Off FoxPro. Double click on My Computer. Double click on Folder Temp. You should see the following:
 
 
Using the mouse, double click on Main.PRG. This will start the main program above. If you have followed the directions carefully, your start program should produce the following browse window within FoxPro.
 
 
Double clicking on any PRG file should launch FoxPro (if it has been properly installed on the computer) and execute all of the lines of code in the PRG file just as if they had been entered one at a time in the command window.  Close the browse window and do the following:

Set Default to C:\Temp          <-- Sets the default directory to the temp folder on the hard drive
Do Main                                 <-- Attempts, unsuccessfully, to execute program Main.PRG within the default directory
                                                           (which is c:\temp). The error will generate the following message:
 

 
Close the error window (OK) and do the following:

Do C:\Temp\Client\Main         <-- Attempts, successfully, to execute program Main.PRG within the directory
                                                          C:\Temp\Client. The program will once more execute just as it did by double
                                                          clicking on the Main.PRG icon above.

When your default directory contains your Main.PRG you can simply do the following:
 
Do Main         <-- Attempts to execute program Main.PRG within the current default directory.

55] Write a program, called DisplayBald, which (1) sets the default drive to C:\Temp\Client, (2) opens the client database table, (3) clears the display window, (4) creates and activates a large window called OutputWin [ title = Display Of The Bald Folk!], (5) displays your name in the center of line 1, (6) displays line 2 as a blank line, (7) displays the the name and phone of all bald people, (8) creates a wait window which says "Hit Any Key To Continue" and maintains it until either the user hits a key or waits 10 seconds, (9) deactivates the OutputWin,  and  (10) exits foxpro. Test the program!

56] Modify Command Main. Make the following changes and save. Modify Command DisplayBald replace set default with the following two lines.
 
* Set Default to C:\Temp\Client
Set Default to A:\Client

The Main program should now consider the default directory to be A:\Client.  The DisplayBald  program should now consider the default directory to be A:\Client.

57] Quit FoxPro. Make at least two  back-up copies of this folder on other disks!   Copy directory C:\Temp\Client (including contents) to two separate floppy disks. Delete the C:\Temp\Client from the computer. Make sure that your backup copies look ok!

58] Turn Off FoxPro. Place a one of your two Client floppy disks in drive A (top-right).  Double click on My Computer. Double click on Floppy drive A. You should see the following:
 
 
Using the mouse, double click on Main.PRG. This will start the main program above; it should execute from your floppy disk. Try It! Exit FoxPro when done.

Using the mouse, double click on DisplayBald.PRG. This will start your DisplayBald program above; it should execute from your floppy disk. Try It! Do not exit FoxPro. Your solution should look something like the following:
