IF statement Syntax

[Danny Wheeler]

I am trying to write an IF statement to suppress all but a subset of messages.  Is this the correct syntax to use in an IF statement or can the statements even be this complex?  Or does this not do what I think it does?

0(0).PV1(0).#10(0)  ne =OBS ||  0(0).PV1(0).#10(0)  ne =NRY ||  0(0).PV1(0).#10(0)  ne =OOB ||  0(0).PV1(0).#10(0) ne =OBV  

Thanks.

Hello Danny – That syntax seems OK but the boolean logic in that statement is going to be true 100% of the time.  if you want to execute the “if” when PV1:10 is one of {OBS,NRY,OOB, OBV}, then the “ne”s should be “eq”s  or if you want the opposite then you need to change your “||”s to “&&”s

I want only these messages {OBS,NRY,OOB, OBV} to not trigger the IF statement (suppress).  What I need is everything that is not {OBS,NRY,OOB, OBV} to trigger the IF statement and suppress.  Am I using the wrong logic here and if so how do you recommend doing this in an Xlate?

Danny,

You could do this 2 ways and it would work but based on your desire to have the SUPRESS activated when the MSH-10 has certain values then

I would try using EG with the connector being || (or).

so IF MSH-10 eq NRS || eq NRY || eq OOB || eq OBV

How about changing the NE to EQ and place the suppress in the main logic.

That way if any are those values, it should suppress them.

Just a thought.

Just a little tip for those behind you that may troubleshoot an issue later:

Whenever I place a suppress in an xlate, I always put a copy statement (that copies nothing) just before the suppress that simply has an echo statement in it.   The echo statement will give the reason why the message was suppressed and will print to the log file.  

Sometimes the suppresses can be buried and hard to find in an xlate.   Being able to see that echo in a log file has helped me in the past.

Thanks….

Thomas.  This would be great tool.  Can you please tell me how you place the echo in the copy?  I am completely new to Cloverleaf and the syntax is what really has me confused.  Thanks.

Hello Danny,

If I read your second post right, you want to exec a SUPPRESS when PV1:10 is NOT one of {OBS,NRY,OOB,OBV}  so you want to “AND” (&&) and not OR (||) your individual “ne” conditions in the original “IF” statement like this:

IF   0(0).PV1(0).#10(0)  ne =OBS &&  0(0).PV1(0).#10(0)  ne =NRY &&  0(0).PV1(0).#10(0)  ne =OOB &&  0(0).PV1(0).#10(0) ne =OBV

  SUPPRESS

(no else)

re the echo statement, just make a COPY operation like Thomas suggested and put it above the suppress inside the if.

source: 0(0).PV1(0).#10(0)

dest: @scratchVar

in the “pre-proc” make sure TCL is chosen and put in this code snippet as a starting point. once you get comfortable with TCL and the xlt parameters you can get more complicated than this.

set temp [lindex $xlateInVals 0]

echo “suppressing message: PV1:10 is “$temp””

When you run the xlate tester then when the copy statement containg this pre-proc execs you’ll see the output and when you run for real it’ll  show up in the process log file.

To dumb it down a little …

(because clarity can save time in the future)

(although this is admittedly bigger and slower),

… you could do something like this:

Copy {OBS,NRY,OOB,OBV} to @RightOnes

Copy 1 to @Trash

….

Copy 0(0).PV1(0).#10(0) to @ThisService

If @RightOnes ct=@ThisService

Copy 0 to @Trash

If @Trash

 Suppress
