Each CPU registers jobs of its own in the form of nodes in a normal node queue, executes the registered jobs in a registration order, has a queue (remote node queue) for registering a job requested by another CPU in the form of a node, and executes the remote nodes in a registration order as in the normal nodes. When the first CPU causes the second CPU to execute a job, the first CPU transmits the job in the form of a node processed by the second CPU. The second CPU registers the received node in the remote node queue and executes it as in the normal node. The second CPU sends back, to the first CPU, the processing result of the received node in the form of a node processed by the first CPU, as needed.

Method for execution of program steps by a remote CPU in a computer

An information processing method and apparatus includes elements and steps to rapid figure editing and its execution environment by quickly executing a program and a file from a diagram showing a flow of the program and file. According to the invention, a rectangular figure object in which a line width is set to '0.2 mm', a line type is set to 'solid line', and a line color is set to 'black' and which is filled by a pattern of a 'diagonal-1' of 'red' is pasted to a drawing sheet by using a mouse or the like by the user. After a character attribute 'dir' was pasted to the rectangular object by using a keyboard, for example, when an instruction to point the rectangular object by using the mouse or the like or to depress a button of the mouse while depressing a control key of the keyboard, or the like is performed, a command interpreter stored in a memory device is activated by a CPU, the character attribute 'dir' of the rectangular object is read out, the characters 'dir' are sent to the activated command interpreter, and the computer command 'dir' is executed, so that the above object can be accomplished.

In editing a program, when a reference variable name of a predetermined program line is designated, a line variable i (its initial value is 1) and line information n are compared. If i.gtoreq.n, the processing is ended. If i&lt;n, a check is made as to whether the line i is a variable definition area. If the line i is not the variable definition area, the line variable i is incremented and the process is repeated. If the line i is the variable definition area, the line i is searched for the reference variable name. If the reference variable name is not found, the line variable i is incremented and then the process is repeated. If the reference variable name is found, the line information and the text information are stored in an INSERT buffer 23-5. The pieces of information are stored in a variable definition table 51 in an order of reception. Finally, the variable definition statement stored in the variable definition table 51 is displayed.

Program processing to facilitate program editing

A pattern editing apparatus includes a selector for selecting a plurality of patterns to be object patterns for an editing process. The plurality of patterns are displayed in a first area on a screen. The pattern selected by the selector is displayed in a second area on the screen. The apparatus also includes a provider, responsive to the selector, for providing a pattern for coupling the selected patterns displayed in the second area. The pattern coupling represents a flow chart processing relationship among the selected patterns. Also provided is a generator for generating a signal responsive to the absence of any pattern representing a flow chart processing relationship in the selected patterns, and an adder for adding the pattern representing the flow chart processing relationship as an object pattern of the editing process.

An information processor includes a coordinate analyzer which analyzes input coordinate information, and a marking device which marks a desired coordinate. A memory stores marking coordinate information analyzed by the coordinate analyzer, and includes a mark name marked by the marking device. A display device displays the marking position in a display area based on marking information stored in the memory by designating the mark name when the marked coordinate is not present in the display area, when changing the display area.

Information processing apparatus and method

An information processing system having a memory for storing a plurality of programs executed in a parallel processing manner, an instruction interpretation section for interpreting instructions in the programs, and an instruction execution section for executing the interpreted instructions. Queues for registering the numbers of the steps of the programs to be executed, wherein the numbers of the steps to be executed next are registered in the queues, the number of each step registered in the queues is read out, the processing to be performed in accordance with the step corresponding to the step number read out is interpreted, and instructions are given to the instruction interpretation section according to the content of the step interpreted. The step numbers of other steps to be executed are registered in the queues, and the plurality of programs are executed in parallel based on the order of the queues.

Information processing in which a simulation of parallelism is achieved

In a method for executing a program for sequentially reading step information registered in an execution queue in the order of registration in order to permit the modification of a branch-to address with ease and without error when the modification of the branch-to address is instructed during the debugging of the program, the step information which is no longer the branch-to address due to the modification is searched in response to the branch-to address modification instruction, the retrieved step information is erased from the execution queue, and step information which is a new branch-to address is registered at the position of the erased step.

An information processing device which operates under a multiprogramming system stores instruction words and an execution condition word for each of those instruction words as a pair in program memories, judges whether or not an instruction can be executed on the basis of its execution condition word and executes the instruction when it is judged to be executable. An information processing device which operates under a multi-CPU system connects a plurality of memories to a plurality of CPUs. The plurality of memories store the global variables accessed most frequently by the CPU with which their own memories are connected.
