Abstract

PURPOSE:To save time and expense for preparing temporary data by taking out and combining data elements from tables prepared for each element unit of data by using random numbers generated by a random number generating device and preparing specified data. CONSTITUTION:A random number generating device R, element taking out device P, element combining device J and an output device O are provided under control of a main controlling device M. Element tables T1-Tn are provided under the element taking out device P; a joint buffer B is provided under the element combining device J; and a file F is provided under the output device O.

Data elements are selected for each element and taken out by the taking out device P using random number generated by the random number generating device R. Each element thus taken out is stored in the buffer B by the combining device J and combined to prepare 1 data, and stored in the file F through the output device O.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a program test) in which data of a mask file to be used is generated by random numbers generated by a random number generator from a table prepared for each element of data. This relates to a data creation method for a mask file that is extracted, combined, and created using .

[Prior art and problems]

When programming a data processing device,
The mask file is used to test and depack the program. If data from the mask file that is actually used is used to test a program like this, the data in the mask file that will actually be used may be destroyed due to a program error, or the data may be mistakenly transferred to the mask file. There is a risk of being overworked.

For this purpose, a test mask file is generally prepared.

For example, there is a customer mask, which consists of multiple records, and a code stores information about one customer. The code is divided into items, and the customer code, customer name, customer address, etc. are stored in each item.

Conventionally, the methods of creating data for testing mask files are two methods: preparing real data on an external medium and inputting it into the mask file through batch processing, and two methods: inputting real data from a display or using a card. There is a method of punching and inputting data to create data one by one.
Both methods have the drawback of requiring a great deal of time and expense.

[Purpose of the invention]

The present invention overcomes the above-mentioned drawbacks.

Used for testing programs with less time and cost1-
The object of the present invention is to provide a method for creating data in a master file that can create data in a master file.

[Structure of the invention]

To this end, the mask file data creation method of the present invention is a mask file data creation method that creates data that can be divided into a plurality of elements and stores it in a mask file, and a random number generator that generates random numbers. A device, multiple element tables that store multiple elements that make up data corresponding to the multiple elements mentioned above, a combination buffer that stores each element that makes up a data unit, and a mask file that stores data. , and a control device that performs overall control, and the control device sequentially controls each element constituting the data,
The random number generator generates a random number, extracts an element from the element table based on the random number, stores the extracted element in the combination buffer, and stores each element constituting a data unit in the combination buffer. is characterized in that it is configured to check whether or not the data unit has been stored, and to store the geocore data unit in the mask file on the condition that each element constituting the data unit has been stored. It is.
