A Guide for developing custom PDL files

[Jon Blanchard]

Is a developers guide available for creating custom PDL files?  I would like to create one for communication between two threads in different processes, that don’t need to spend extra processing time on parsing an HL7 ack.

Thanks.

Why not use length encoded tcp/ip for the protocol?

I would then use a simple Tcll proc to provide the ack (you do want one but it does not need to be HL/7) – somethiing like ‘ack’.

On the sending thread then do whatever you want with the acknowledgment (some people just use hcitpsmsgkill for handling the reply).

Someone at McKesson did write a PDL that returned a one-byte response and it was in use at my previous employer; the PDL was used at both ends of the loop connection and did the same thing that you are suggesting, but without any additional thread config.  Once that employer migrated away from Cloverleaf, the PDL file disappeared.  Perhaps someone in this community is using it at their installation and would be willing to share it, as we are using the McKesson branded version of 5.8.

length encoded tcp/ip is not an additional config  it is just a different protocol so instead of specifying the pdl protoccol specify the tcp/ip protocol.

I can provide a proc that returns ‘ACK’. If you would like it email me.
