Russel,
Is is as you woud ex... imagine-- argv.

$expect script param1 param2 ... paramn

All the parameters are found in the list 'argv' , so if in script
...
set argc [llength $argv]
for (set i 0) {$i < $argc} {incr i} {
                puts "arg $i: [lindex $argv  $i]"
}

...

Then the script will spit out:

...

arg 0: param1
arg 1: param2
...
arg n: paramn
...

As in D.Libes' "Exploring Expect" (Oreilly)
