Alan,
The answer is no for NetLogo 3.1, but YES for NetLogo 4.0
(beta 3).

In NL4, all three settings in the Slider's dialog box can be
constant 
values, global variables, or reporters. For example, to see
how they 
can be global variables, paste this into the Procedures of a
new NL4.0 
model:

globals [ slider-min slider-max slider-incr ]

to test
   set slider-min 7
   set slider-max 27
   set slider-incr 2.5
end

Then in the Interface, make a slider and type the three
global variable 
names into the dialog box for the max, min, and increment
values. Then 
type 'test' into the Command Center, or just set these
variables to 
different values and see the results on the slider.

So to change the settings, you set the global variables. To
use them, 
you just use the global variables.

HTH,
Jim
