A virtual machine system has a processor operating as a base machine which includes a plurality of groups of registers, such as data registers, address registers and instruction address registers which are selected according to identification data identifying individual virtual machines. A respective group of registers is allotted to each virtual machine and to the virtual machine monitor in the system. A status register file is provided to effect selective access to a respective one of a plurality of status registers in the system in accordance with a virtual machine number. An interrupt processing portion is provided comparing the value of an interrupt mask level of the status word of a corresponding virtual machine with an externally generated interrupt level to control interrupt processing.

The interactive character font pattern creation, editing and composition control device comprises transforming a printed font into a dot string data of '0', '1' on a drum scanner or the like, expanding the dot string data of font patterns loaded in a font pattern file to a storage to displaying on a display terminal. When a terminal user executes commands for noise deletion, automatic centering, translation, rotation, scaling/zooming, and creation of a revised font pattern through composing a plurality of font patterns to the font pattern given on a display screen, the device applies an operation according to the commands with an original font pattern expanded in the storage as input, loads it then in a storage for storing a current font pattern and displays the current font pattern on the display screen of the terminal.

Phrases in an input character string are registered in a table (phrase table), frequencies of occurrence of those phrases are counted and registered in the table, the phrases having high frequencies of occurrence are selected and macro codes therefor are determined, and those macro codes and the corresponding phrases are paired and registered in the macro table. A content of the macro table thus prepared may be displayed on a display screen. Thereafter, a user can enter a desired phrase by keying the corresponding macro code.

Method for automatically registering frequently used phrases

An argument which is a set consisting a global variable in a procedure to be called, a designation symbol representing localization and a variable or constant on a procedure call side is designated as an argument of a procedure call statement of a program, the global variable in the called procedure is localized in the procedure in response to the designated information, and the value of the variable on the procedure call side which is a member of the set is used as the initial value of the local variable. An argument which is a set consisting of a local variable in a procedure to be called, a designation symbol representing globalization and a variable on a procedure call side is designated as an argument of a procedure call statement of a call program, the local variable in the called procedure is globalized in response to the designation information, and a data area which is the same as that of the variable on the procedure call side, which is a member of the set, is used. A procedure call statement is designated by omitting an argument of a procedure call statement of a call program, the omitted argument in the procedure is processed as a global variable, and a data area which is the same as that of a variable on the procedure call side, which has the same name as that of the argument in the procedure, is used.
