<p>PURPOSE:To simply attain multi-window by the user by using a console handler so as to manage altogether a display request issued individually from different kinds of operating systems OS so as to exclude the difference in the character processing algorithm in each OS. CONSTITUTION:When a real time core 1 of a multi-operating system is subjected to macro call by an OS 2, the content of the macro call from the OS 2 is analyzed in the OS management routine during the operation and whether or not an OS changeover request is given is checked. When the request is an OS changeover request, the despatch processing is applied as it is, and in case of the changeover request, after an ID number of the OS during operation is written in the OS flag 5, despatch processing is applied. When a display request is issued from the OS 3, the console handler 4 is started by the direct software interrupt. Then the handler 4 uses the OS flag 5 and the console table 6 to exclude the difference in the character processing algorithm in each OS.</p> |
