      Hello all,

      I can’t figure out a way of doing this. I am trying to create a sequential number to place in a certain segment. I need this number to be unique each time (so it has to remember the number it used in the last message).

      I was thinking of some sort of global variable that Cloverleaf could keep track of and use, but I can’t seem to find anything on it. I am just looking to have a number count up each time, without ever repeating.

      Please let me know if you are aware of anything and thank you in advance.

          Jon,

          If you want this value to survive shutdowns of various types, it needs to be disk-based rather than held in memory with a global. Check out the followoing tcl commands:

        • CtrCurrentValue

          CtrInitCounter

          CtrNextValue

          CtrResetValue

        Jon,

        We use the counter file function provided with Cloverleaf.

        In Help under Refernce/Tcl Extensions/Counter Commands and Counter Extensions you will find documentation.

          Like those guys said  ðŸ˜† Great thing to use if you need your MSH id number to be unique.

            I have an old clovertech post showing the use of the counter file technique previously mentioned by others

            Look at my proc called

                tps_fileset_outbound

            at this URL

                <a href="https://usspvlclovertch2.infor.com/viewtopic.php?t=1663&#8243; class=”bbcode_url”>https://usspvlclovertch2.infor.com/viewtopic.php?t=1663

            to see a tangible example of using the counter file technique then adapt to your needs if you like.

              Is it possible to make these calls within the TCL section of the XLATE or do I have to code it outside of the XLATE and call it?

              Do I just give it the path to the file and use the retrieve and increment variation? I am new to the external file calls.  

              Thank you

                if you going to use in the xlate, you can set up your own counter in the translation tool.  Then use MATH or whatever to change number.

                I am not sure if you can access a .ctr file from inside a the translation..never tried that.

                  Can I set up a number that is being counted up from within the translation tool that will persist? I need it to always remember the last number that was used. I was hoping to try to do it from within the XLATE TCL section.

                  Thank you

                    the variable you use as the counter in the translation will reset.  try using global variable instead.

                      Jon,

                      I have a proc you can call inside an Xlate – just pass it parameters.

                      If you want it along with user doc – email me – my email is part of my profile

                        Jon,

                        You’re trying to make this more complicated than it really is. You can use the Ctr* calls anywhere in the Xlate where you can use Tcl. The counter value is held on disk. If you don’t ever want the value to reset, then give it an impossibly large rollover value when you initialize it.

                          Jon,

                          I echo what Chris is saying.   Also, if you want your counter to start at a specific number, you can specify that when you initialize it.   You don’t have to start at 1, that is just the default.

                          Hope this helps….
