Abstract

PURPOSE:To prevent a malfunction by disabling a RAM file to be set while a floppy disk is set in a disk drive and outputting a message indicating that the RAM file is already set when the setting of the floppy disk is tried in the RAM file setting state. CONSTITUTION:The control moves to a RAM file switching process 2 with a RAM file setting command 1 and then moves to a floppy disk setting judgement process 3 from the RAM file switching process 2, and the status about whether or not the floppy disk is set is referred to. When the floppy disk is set, the control moves to an output process 4 for a message indicating that the RAM file is not set and the RAM file is not set. When the floppy disk is not set, the RAM file setting state is written in the status in the RAM file switching process 2 and the state of RAM file setting 5 is entered. Consequently, the malfunction such as misaccess to the file and the breakage of the medium is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a terminal device, particularly an area (R) created on a main memory.
This invention relates to a terminal device that allows AM files to be used logically in the same way as floppy disks.

Conventional terminal devices of this type have RA when a floppy disk is set in the floppy disk device.
There was no function to determine whether or not to perform switching between M files and floppy disks. Also, even when a RAM file was set, there was no message even if I inserted a floppy disk.

[Problem to be solved by the invention]

In the conventional terminal device described above, even if a floppy disk was set in the disk drive, switching between the RAM file and the floppy disk could be performed. Also, when a RAM file was set, no message was output even if a floppy disk was inserted, so if you forget to remove or install a RAM file, you may unknowingly try to access another medium. It has the disadvantage that it cannot be accessed, or that data may be accidentally destroyed by accessing another medium, or that other data may be read.

[Means for solving problems]

The terminal device of the present invention is a terminal device having a RAM file setting function, and includes: a first status indicating whether or not a floppy disk is set in the disk drive; and a second status indicating the setting of the RAM file. , means for determining whether switching processing is enabled for the RAM file based on the value of the first status; and if an attempt is made to insert a floppy disk while the RAM file is set, the RAM The present invention is characterized by having means for outputting a message whose file has been set.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

In the figure, 1 is the RAM file setting command, 2 is the RA
M file switching process 3 is a floppy disk setting judgment process, 4 is a message output when the RAM file is not set,
5 is RAM file setting, 6 and 8 are floppy disk set, 7 is RAM file setting judgment process, 9 is RA
This means outputting a message with M file settings.

The process moves to RAM file switching processing 2 according to RAM file setting command 1, and RAM file switching processing 2
Then, the process moves to floppy disk setting determination process 3, and the status of whether or not a floppy disk is set is checked.

If a floppy disk is set, the process moves to message output 4 where no RAM file is set, and no RAM file is set. Also, if the floppy disk is not set, the RAM file switching process 2 will
The AM file setting state is written in the status, and the state becomes RAM file establishment 5.

If the floppy disk is set 8, the process moves to RAM file setting determination process 7 to check the status of whether or not a RAM file has been set, but the floppy disk is set without any message. If you set 6 floppy disks, use RA as in 8.
The process moves to M file setting determination processing 7, and a RAM file setting completion message output 9 is performed.

〔Effect of the invention〕

As explained above, in the present invention, when switching between a RAM file and a floppy disk in a terminal device with a RAM file function, the RAM file cannot be set while the floppy disk is set in the disk drive. Furthermore, if an attempt is made to set a floppy disk while the RAM file is set, a message indicating that the RAM file has been set is output, thereby preventing erroneous operations such as file access errors and media destruction.
