Abstract
The author developed the generalized computer systems for input and output, which can be used for developing the various agricultural softwares. The systems may be defined as the computer tools for developing the application softwares also. Generally speaking, as there are many databases which has the special format of the spread-sheet style, the systems developed are characterized by the tabular style systems for inputting the data, which fulfil the many functions for editting the data. And also, in the systems, several convenient sub-systems such as the generalized programs for outputting the culcurated data, for displaying the menues, graphs and titles, are included, and the user of the systems can compose the original system quickly as he likes it. The systems are developed by using the C language (Microsoft C Version 5.1), and can be executed using the NEC 9801 series personal computers.
