Abstract

PURPOSE:To support a program using a CRT in various modes under the same circumstance by providing an I/O monitor means, a data escaping means, an LSI status information storing means and a program monitor etc. CONSTITUTION:When a program A executes the occupancy declaration of a CRT 1 and a drawing and displaying is executed at a CRT mode A, input and output data to an exclusive-use controller LSI group 2 are supervised by an I/O monitor means 3. Necessary status information are stored to an LSI status information storing means 5 by a data escaping means 4. After that, the mode is changed from the CRT mode A to a CRT mode B through a program monitor 6. Further, when the CRT mode A is used again, the information stored to the means 5 are outputted to the group 2 by a status restoring means 7. Accordingly, the program A can be drawn and displayed to the CRT1 as the continuation of the preceding CRT1. Namely, even the program to use the CRT1 at the different mode can be supported in the same circumstance.
