Hello,

What I need to do is set the TXA.17 field to a certain string based on a value in the OBX.5 [repetitive] field. When testing my code, what looks to be happening is that I’m able to find the OBX.5 value, but only AFTER it processes thru the TXA segment. Therefore, when I put the message back together, the TXA.17 isn’t changed correctly.

What I need to do is somehow process thru the OBX segment prior to the TXA. Is this possible within a single tcl-proc? If so, how?

Thanks,

Josh

  You have a few options.
  
  1) you can loop through the message twice – once to get the OBX info you need, then a second time to make changes to the TXA.
  
  2) you can do something similar to #1, but use your regexp and/or string tools to find the OBX(s) in the message string, then loop through the message making the required TXA changes.
  
  3) Or, build a library of Tcl procs to read and write HL7 messages (my personal favorite). That way, you can parse the message, direct-access the OBX info you need for your decision, then write required changes directly to the TXA. When you’re done, encode the modified message and send it on its way.
