history [n] [-x]
_________________________________________________________________

The YAN history command displays the total number of recallable
commands and a list of them.

The YAN history n command sets the number of recallable commands
to n. 0 will stop new command saving, but has no effect on
previously stored history or recall. -x will set the minimum
length of a command to be logged, a la 4DOS. n and -x can be used
separately or together, but if together n must be first.

In the command and ftp sessions the UP arrow and the DOWN arrow
will recall commands from a circular list which defaults to ten.

>> Example: history 24 -4
Sets the history file to log 24 commands of 4 characters or more.
