Modify script to allow more than one variable (pool).

This iCall script works great, but you can only add one variable (one pool name). Therefore, I have to create a separate script for each pool I want to check, which is not desirable. I need help finding the best way to modify the script so that multiple pool names can be added. That way I can have just the one script that checks multiple pools. 

admin@(f5-device-001)(cfg-sync Standalone)(/S1-green-P:Active)(/Common)(tmos) list sys icall script check-members-script 
sys icall script check-members-script {
    app-service none
    definition {
        set pn "/Common/pool-fooapp.example.com"
        set total 0
        set usable 0
                foreach obj [tmsh::get_status /ltm pool $pn detail] {
                    puts $obj
                    foreach member [tmsh::get_field_value $obj members] {
                        puts $member
                        incr total
                        if { [tmsh::get_field_value $member status.availability-state] == "available" && \
                            [tmsh::get_field_value $member status.enabled-state] == "enabled" } {
                                incr usable
                       }
                 }
            }
            if { [expr $usable.0 / $total] < 0.7 } {
                tmsh::log "Available pool member threshold reached for $pn"
       }
    }

    This appears to be working well:

    admin@(f5-device-001)(cfg-sync Standalone)(/S1-green-P:Active)(/Common)(tmos) list sys icall script check-members-script 
sys icall script check-members-script {
    app-service none
    definition {
        set pool_names "/Common/pool-fooapp1.example.com /Common/pool-fooapp2.example.com /Common/pool-fooapp3.example.com"
        foreach pn $pool_names {
        set total 0
        set usable 0
                foreach obj [tmsh::get_status /ltm pool $pn detail] {
                    puts $obj
                    foreach member [tmsh::get_field_value $obj members] {
                        puts $member
                        incr total
                        if { [tmsh::get_field_value $member status.availability-state] == "available" && \
                            [tmsh::get_field_value $member status.enabled-state] == "enabled" } {
                                incr usable
                       }
                 }
            }
            if { [expr $usable.0 / $total] < 0.7 } {
                tmsh::log "Available pool member threshold reached for $pn"
        }
      }  
    }
