GENERAL USE

HEXED.OPA should be in the APP directory of an SSD or internal memory.
Install HEXED.OPA. (See Psion Series 3 user manual for details on how to do 
this)

HEXEDITOR will automatically save the current file in use if it has been 
changed. This will happen when you select New, Open or Exit from the 
Main Screen menu or the System screen.
Maximum file size 16000K.


MAIN SCREEN

HEXEDITOR will accept only hex values. (0-9, A-F) Each pair of values 
represents one byte.

To change position, use the left arrow key to move left, the right arrow key 
to move right, the up arrow key to move a line up, the down arrow key to move 
a line down. (The screen will scroll  if necessary) Use the Psion key and 
Home key to move to the top of the file, the Psion key and Pg Up key to move 
a screen up, the Psion key and Pg Dn key to move a screen down and the 
Psion key and End key to move to the end of the file.

To enter a value, move the cursor to the correct position and start typing. 
Whatever you type will overwrite the existing value.
To delete a value, move the cursor to the correct position and press the 
Delete key. The byte under the cursor will be removed and all following 
bytes will move one position up.
To insert a value, move the cursor to the correct position and press the 
Space bar. All the bytes under and following the cursor will be moved one 
position down and a zero value inserted. This can now be edited.

Press the HELP key for help.
