How to use the Control A Editor

Main Window:

The List Box:

The list box contains ninety-six distinct commands each corresponding to a specified character/hexadecimal.  These commands are stored in a file and can be modified with this program.

The keyboard or the mouse can be used to scroll through the 96 different commands. Once a command is highlighted, clicking on the Edit button brings up the Edit Dialog allowing for modification of the existing command.  In addition, double clicking with the mouse or pressing the Enter key will also make the Edit Dialog show up.

Delete button:

Deletes the currently selected List Box command.

Cancel button:

Closes the program and disregards changes.

OK button:

Saves the changes that have been made.

Help button:

 Opens up this help file.

Edit Dialog:

Char edit box:

Displays the selected ASCII code as a character.

This edit box is Read-Only.

Hex edit box:

Displays the selected ASCII code as a Hexadecimal.

This edit box is Read-Only.

Command edit box:

This edit box has been customized to accept only Hexadecimal input.  Therefore, pressing non-hexadecimal keys will have no effect.  Furthermore, this edit box is on Overtype mode meaning text is replaced as new text is typed.  Therefore, one cannot insert text in the middle of the string because once a valid character is pressed; the next non-white space to the right of the cursor is replaced.  The space bar also has no effect in this edit box because the input is automatically formatted to easily distinguish each BYTE.

The delete key has been disabled and thus only the backspace key can be used to erase.  If there is a single lone character to the immediate left of the cursor, pressing the backspace key will delete that one character.  Otherwise, it will delete in pairs.

For Example:	AA 33 22 11 9D EC F

If the cursor was located to the right of the F, pressing the backspace key deletes the F resulting in the following string:

AA 33 22 11 9D EC F   ----->	AA 33 22 11 9D EC

If the cursor was located to the right of the D or to the immediate left of the E, pressing the backspace key has the effect of deleting the D and the 9 resulting in the following string:

AA 33 22 11 9D EC F   ----->	AA 33 22 11 EC F

Pressing the Cancel button will disregard the changes.  Pressing the OK button will update the List Box in the main window to show the newly modified command.  However, if there is an incomplete command written, pressing the OK button will bring up a message box prompting for a proper command to be entered into the edit box.  For example:

AA BB 32 9D AA 8	improper command

AA BB 32 9D AA 8A  	proper command
