ECHO Commands
ECHO is really two commands: one to control the ECHO status (whether the command lines in the file will be displayed, or just the messages they generate) using the ON and OFF arguments, and one to display text on the console. Considering the case of the first usage, if a batch file is always invoked or called by another, only the first one need have the @ECHO OFF command, which will remain in force as long as COMMAND.COM remains in batch mode. Note that this does not affect secondary command processors.
ECHO, without any arguments, simply displays the echo status: either ON or OFF.
ECHO seems to have been provided as a means of issuing messages to the user, but there are other uses. The not well documented syntax ECHO. (note the '.' at the end of the command) ECHOs a blank line. This is quite useful, when piped to certain commands, for supplying the required to terminate the command.
