Program 20 for accessing display device 100
0 includes a guidance display area 201, a product code input area 202, a product name display area 203, and screen information 2.
In the example shown, the screen information 210 has four rows. Each row of the screen information 210 includes a number field, a row field, a digit field, a type field,
It has a length field and a literal field. The Kaidance display unit 201 reads the first and second lines of the screen information 210 where the type field is fixed, and sends the display data DI and Dt to the display device 100.

Display data D says, "Display the 'Product Code' in 5 rows and 5 digits," and display data D says, "Display 'Product Name' in 5 rows and 20 digits."0 When the display data D and the receiver are taken, the display device ff10
0 displays the character string "Product Code" in 5 rows and 5 digits of the display screen, and displays the character string "Product Name" in 5 rows and 20 digits of the display screen.

Product code input section 2 after guidance display section 201
02 is activated. The product code input unit 202 reads the line in the screen information 210 where the type is input. In the illustrated example, the third line of the screen information 210 corresponds to this.

The line field of this line is 6, the digit field is 5, and the length is 5, so the product code input field 202 is "6 row 5.
Send display data D that says "Cancel the input prohibition for the length of 5 digits starting from the 5th digit" to the display device 100. When the display data D is received, the display device 100 will display the data from the 6th row and 5th digit on the display screen. Remove the input prohibition in the area for 5 characters.For example, write ``rl'' in this area of the display screen.
When the character string 23J is input from the keyboard, the display device 100 sends back to the program 200 data D4 indicating that the input data is r123J.

This input data is stored in area A1 within program 200.

After the operation of the product code input section 202 is completed, the product name display section 203 is activated. The product name display section 203 reads the line where the type is display in the screen information.
In the illustrated example, the fourth line of the screen information 210 corresponds to this. This row has a row field of 6, a column field of 20, and a length field of 5.

The product name to be displayed is stored in area A2 in the program 200, and is rABCJ in the illustrated example. The product name display unit 204 sends display data D5 and D6 to the display device 100. The display data D is such that "the output area is 6 rows and 20 columns", and the display data D,
When receiving the display data D and D6 which indicate that the output data is "ABCJ", the display device lOO displays the character string rABC, on the 6th row and 20th column of the display screen.

[Problem to be solved by the invention]

When changing the screen information to change "Product Name" to "Delivery Product Name", for example, change the screen information 2 in the program 200.
The guidance in 10 (second line) must be changed. Changing a program is not easy because it requires translation of the source program and combination of the target program.

The present invention was created in view of this point, and is an access information system that allows dynamically changing access information used when accessing an input/output device such as a display device or a printer device. The purpose is to provide a dynamic change method for
