How AutoScript Supports Intelligent Agent Technology

We implement the Intelligent Agents in Mykosmos/BOS using AutoScript as well. To support this technology, AutoScript implements some extra keywords and constructs to do the job.

start_agent_info...end_agent_info

We use them to define the basic elements of the agent. For example:

start_agent_info

       AgentName = “first_agent“
       AgentDescr = ““
       AgentLanguage = ““
       __timer_interval = 0{....define (in seconds) the timer interval for the wake up}
       __is_registered = 1{.....1=the agent keeps trail to database, 0=starting without trail}
       __delete_on_termination = 0{....1=the agent frees itself when terminates its task}

end_agent_info

start_action...end_action

They include the code that executes when the agent is activated.

{....................................ACTION CODE..............................................}

start_action

       callwait bpm_assign_job (“do job one“,“John“,““)

       callwait bpm_assign_job (“do job two“,“Peter“,““)

       callwait bpm_assign_job (“do job three“,“Matthew“,““)

end_action

start_bpm_activity...end_bpm_activity

start_bpm_subactivity...end_bpm_subactivity

start_bpm_validation...end_bpm_validation

We use those keywords to define user activities. They include the code of the agent executed on the client-side. For example:

start_bpm_activity “New Request“

       start_bpm_subactivity “Define new request‘‘s elements“

         rec = bpm_getrecid()

         if rec = 0 then

                 call OpenFormModal(“ptAppend“,“REQUEST02.FM“,“WORK.REQUEST“,1,“?=REQUEST“)

         else

                 expr = strcat(rec,“=REQUEST“)

                 call OpenFormModal(“ptEdit“,“REQUEST02.FM“,“WORK.REQUEST“,1,expr)

         endif

       end_bpm_subactivity

         start_bpm_validation

                 result = 1

         rec = bpm_getrecid()

         if rec = 0 then

                 call message(“Order does not defined!“)

                 result = 0                                         {....do not return to server}

         endif

         end_bpm_validation

end_bpm_activity

We can have any number of start_bpm_subactivity...end_bpm_subactivity into a user‘s activity.

callwait

That is used only for bpm_assign_job and agent_run. The agent action code does not continue until those procedures are returned control to the agent. For example:

callwait bpm_assign_job (“do job one“,“John“,““)

callwait agent_run(ag)

split_in_branches...and_branch...join_branches

We implement parallel splinting in the following example.

split_in_branches

       callwait bpm_assign_job (“do job one“,“John“,““)

and_branch

       callwait bpm_assign_job (“do job two“,“Peter“,““)

and_brach

       callwait bpm_assign_job (“do job three“,“Matthew“,““)

join_branches

a = 10

We will execute the command (a = 10) only after John, Peter, and Matthew finish their activities. In this example, we know the number of parallel splits of the code in advance. Therefore, we have the following construct in cases where the number of parallel splits we define by code (x).

split_for...next_branch

We use this type of parallel splinting when we do not know the number of splits in advance. For example:

     split_for i = 1 to user_count

         callwait bpm_assign_job (“do your job“,user[i],““)

     next_branch

     a = 10

We will execute the command (a = 10) only after user_count jobs are assigned to those users and then return finished by them.
