Variables are useful for giving names to values referenced in a script, especially values that are referenced multiple times. For example,

CommandTerminator = "\r\n"

TFTPServerAddress = 192.168.10.50

TransferFileName= startup-config.txt

@login

@write "copy tftp start"

@write $(CommandTerminator)

@write "$(TFTPServerAddress)"

@write "(TransferFileName)"

@write $(CommandTerminator)
