Hi Audrey,
	One way would be to use the label command -- for example

plot/i=1:10 1/i
repeat/i=1:10 ( label `i` `1/i` 0 0 0.1 @sr@p2(`i`,`1/i`) )

The backward quotes get the numerical value of the enclosed variable.
Two things to note. 1) If a simple numerical value is used as a plot
label it is safer to precede it with a font or pen selector (@sr or
@p2 for example). 2) The demo above shows that the number of decimal
places varies between labels when the values are not integers. In
cases like this you could use something like
	let v=1/i
	let vlab=int(100*v)/100
	repeat/i=1:10 ( label `i` `1/i` 0 0 0.1 @sr@p2(`i`,`vlab`) )
to show at most 2 digits after the decimal point.

Good luck,
Mick
