building an array

[John Harvey]

Hi,

I am working on a potential tcl script to only send adt messages for certain departments.  The thing is, there are 20+ departments for me to filter.  It seemed logical for me to build these departments into an array at startup, then have the array available during runtime.

As I understand TCL within Quovadx, I believe I would need to build the array into one tcl script (as I have posted below), then I would need to add the one script to both the start-up procedures field within the Protocol Properties, AND to the TPS Outbound Data field under the outbound tab.

Am I pretty close on my reasoning?

# Name: filter_hl7_dpt

# Purpose: to filter by department.

#        

# UPoC type: tps

# Args: tps keyedlist containing the following keys:

#       MODE    run mode (“start”, “run” or “time”)

#       MSGID   message handle

#       ARGS    user-supplied arguments:

#              

#

# Returns: tps disposition list:

#          

#

proc filter_hl7_dpt { args } {

   keylget args MODE mode               ;# Fetch mode

   set dispList {} ;# Nothing to return

   switch -exact — $mode {

       start {

           # Perform special init functions

           # N.B.: there may or may not be a MSGID key in args

           build the array here

       }

       run {

           # ‘run’ mode always has a MSGID; fetch and process it

           Filter message here using the array

       }

       time {

           # Timer-based processing

           # N.B.: there may or may not be a MSGID key in args

       }

       

       shutdown {

 # Doing some clean-up work

       }

   }

   return $dispList

}

Can you use a Cloverleaf table to hold the contents of your array?  Then all you need to do is a table lookup when you need to access it.

Hope this helps,

Your logic will work.  But I agree with John why not just build a table and use that. This would make it more easy to maintain. Also makes it easier for other to look at and understand.
