Value history


The values printed are given history numbers by which you can refer to them. These are successive integers starting with one. print shows you the history number assigned to a value by printing `$num = ' before the value; here num is the history number.



p *$


p *$.next

You can print successive links in the chain by repeating this command--which you can do by just typing RET.


print x
set x=5


show values
Print the last ten values in the value history, with their item numbers. This is like `p $$9' repeated ten times, except that show values does not change the history.
show values n
Print ten history values centered on history item number n.
show values +

Pressing RET to repeat show values n has exactly the same effect as `show values +'.
