I would like to get the path of acrobat reader for any unix pc.

right now the path of acrobat reader is hardcoded

BEGIN

if :global.system = 'HP-UX' then
HOST('/opt/Acrobat4/bin/acroread /export/USERGUIDE.pdf');
else
v_path := 'HKEY_CLASSES_ROOT\acrobat\shell\open\command';
v_msg := Win_Api_Environment.Read_Registry(v_path,'',true);
APPID := DDE.APP_BEGIN(v_msg,DDE.App_Mode_NORMAl);

end if;
END;



Like in windows i can code to open acrobat reader whatever the windows with registry

" v_path := 'HKEY_CLASSES_ROOT\acrobat\shell\open\command'; "

is there a way to indicate the same thing for acrobat in unix?

thanks you!
