Hello,

During migration of a clipper application to xBase++ (text mode) I faced a 
need to replace a standart GET reader command, getting the input from Left 
to Right
with a new GET reader command (for Hebrew) getting the input from Right to 
Left.

I need:

1. To toogle between languages: to sent a ctrl-shift or alt-shift ascii code 
to the keyboard.
     I couldn't find the ascii codes for such combination.

2. To move the cursor to the right side of the input field.
     I'm using:    oGet:end().
    It is working.

3. To move the cursor one position from right to left after each Hebrew 
keystroke or space bar: ascii 128 to 154, and ascii 32.
    I'm using:     oGet:pos := Len( oGet:buffer ) - (i++).
    It is working, but not very elegant.

4. Toggling back to English or numbers should use the standard GET reader.


Any help would be appreciated.

I don't think these keys send scan codes by themselves. You can query the
state of these keys however (with appKeyState()) in your event loop after
you checked for regular events.

i do not think tha GET can do it. switch to XbpSLE

hm ... perhaps this help
