Best way to handle null made by xlate

[Tom Schlesser]

I am trying to use a null field as a flag for additional action to take in a Translate.  The issue I am running into is the original message is not sending an NTE 3.  I have attempted to create an NTE three field by using the condition of if NTE 2 = L then make NTE 4 equal to COM.  Now I am attempting to use the tilde (~) to look at the outputted message for the NULL value that I was trying to create in NTE3.  Cloverleaf is unable to recognize the null field.  Is there a better way to handle this?  Is there a way to look for HEX values in a Cloverleaf translate.  I could look for hex values of 4C 7C (L |).  

Any help would be appreciated.  Sample Message below

Thank you

What are you trying to accomplish?  Are you iterating over the NTE segment? Probably as part of a group, possibly?

if 1(0).0(0).NTE(%s1).#3.[0] eq @null

    # Do Something

Just as an example…..This should be true on your second iteration where NTE-3’s value would be @null.

NTE|3|L|Pt is fasting

Hope this helps….
