Changing T back to & – Part 2

[garry r fisher]

Hi,

Some assistance would be appreciated please.

I have the following input – ’73 LEEDS T BRADFORD’

Which I want to be ’73 LEEDS & BRADFORD’

I have the following xlate procedure:

   set tmp [lindex $xlateInVals 0]

   regsub -all {\T\} $tmp {&} tmp

   set xlateOutVals

I know it can be done simpler than this but I was echoing the output to check it at each step.

If I put this as a pre proc I get ’73’ which is what I expect as the HL7 parser will truncate it.

If I put it as a post proc I get ’73 LEEDS T BRADFORD’

Why is the post proc not doing the translate correctly – What am I doing wrong?

Regards

Garry

I’m surely not an expert on Cloverleaf, but since no one else has responded yet, I’ll offer my 2 cents worth.

First a point of confusion.  You say that when you run your code as a pre proc you get the output you expect of just ’73’.  But it seems like you should actually be populating the outbound field with ’73 LEEDS & BRADFORD’, and then maybe the receiving system would truncate it to just the first subcomponent of ’73 LEEDS ‘, but not just ’73’.

As for your main question, I think that is just the way that Cloverleaf works.  I frankly don’t understand why they even have an xlate post proc, but I believe that it’s pointless to put any code there and that the only way you can alter the content of what gets copied to the output record is to use the pre proc.  I hope someone will correct me if I am wrong here.  But is there any reason you felt you needed to use the post proc instead of the pre proc?

Hi,

Greg – Sorry for the confusion. The inbound data is HL7, outbound its a fixed length record. I thought the HL7 parser would work on the xlate splitting the record at the &.

I’ve never got post proc to work either but I tried a number of experiments before wrote this and the text is an abbreviated version of my findings.

Charlie – Thanks. You don’t say pre or post but I’ll try them both.
