Reply To: Add new OBX in an ORU message BEFORE the OBX iterate

What I mostly do is keep track of the number of OBX’s that are translated by means of a list-variable (%l1). For example:

# initialize variable

COPY =0 -> $%l1

# Iterate through OBR

ITERATE group basis 3 variable %g1

 # Create new OBX

 COPY ={new info} -> 3(%g1).1(%l1).OBX

 MATH: ADD $%l1 =1 -> $%l1

 # Iterate through normal OBX

 ITERATE group basis 3.(%g1).1 variable %g2

   # Create new OBX

   PATHCOPY 3(%g1).1(%g2).OBX -> 3(%g1).1(%l1).OBX

   MATH: ADD $%l1 =1 -> $%l1

I hope you get the drift…
