Description

ECHO is a tool created by Stefan Danes. You can find it on Dragon Disk 03.

You can't use it under MSX-DOS 2 / Nextor, because the internal command ECHO is then automatically used.

Command

Effect

  • Displays a blank line or a text on the screen.
  • Can also turn on/off the screen and create a text file.

Syntaxes

  • ECHO <Text>
  • ECHO ON|OFF
  • ECHO <Text>@ > <Device>:<Filename>

Parameters

<Text> is the text to display on the screen. If no text is given, then just a blank line is output.

ON/OFF enables/disables the screen. It's equivalent to DEFUSR=&H44 : X=USR(0) and DEFUSR=&H41 : X=USR(0) in MSX-BASIC.

<Device> is the name for used device. It can only be a disk drive.

If you don't specify the drive, the computer will work with the currently active drive (by default, it's drive A:)

Device type Device name Remark
Disk drive A, B, C, D, E, F, G, H A floppy disk interface can control until 2 drives.


<Filename> is the name of the text file that will contain the text of the ECHO line.

Examples

A>ECHO ECHO AUTOEXEC batch file executed
A>ECHO TEST@ > B:TEST.TXT

Environment

  • MSX1 and higher
  • Only MSX-DOS 1
