Thanks Charles - this looks like just what I need. I'll give it a try.

Re: [Sipp-users] How to code
variable length pause range
(Document link: Don Morrison)
Don,
I have committed some changes that allow you to achieve this functionality.
The basic flow is that the [field0] is read into a newly string variable
type ($1). $1 is then converted to a double value ($2) [new
functionality]. To perform the random sampling, the existing sample action
is used with a uniform distribution from zero to one into $3. Finally, $3
is multiplied by $2 [previously you could only add, subtract, multiply, and
divide by constants], so you have a double value that is uniformly
distributed between zero and [field0]. You can then use this value as the
input to a pause command. Sample XML, with some additional logging so that
you can track what is going on is below.
<nop>
<action>
<log message="[call_id]: Started at [clock_tick]" />
<assignstr assign_to="1" value="[field0]" />
<todouble assign_to="2" variable="1" />
<sample assign_to="3" distribution="uniform" min="0" max="1" />
<log message="[call_id]: Uniform (0, 1): [$3] * [field0]" />
<multiply assign_to="3" variable="2" />
</action>
</nop>
<pause variable="3" />
<nop>
<action>
<log message="[call_id]: Paused until [clock_tick]" />
</action>
</nop>
