Setting a Flag(temp variable) in a XLT Iterate

[Paul Johnston]

In a XLT is it possible to set a Flag ( to Y or N ) in a ITERATE  on its first iteration and then check the Flag on the second Iteration .

Thanks

My original solution of COPY =Y to @Chk2 works.

On subsequent iterations I perform an If @Chk2 eq =Y

Can’t get much simple than that .

For some reason this simple solution was not working earlier and thats

when I was became puzzled and posed my question.

Hi Paul,

I often forgot to initialize the Flag before the iteration. When checking this Flag, Cloverleaf would give an error because the Flag-variable was unknown.

Maybe that’s the case here also?

Paul,

I think the problem may be in your IF statement.  Personally, I have found that if I try to access something like “YES” or “NO” in an IF statement inside an xlate, that the engine doesn’t like it if I say something like “IF @OBX_FLAG eq =Y”.  

Instead I use two “@” variables in my comparison.  I have a variable I use in an iterate for an OBX flag.  Here is how I do it.

First, I declare my variables outside the iteration:

   COPY =NO    @OBX_FLAG

   COPY =YES   @YES

   COPY =NO    @NO

Second, I set up my IF statement as:

   IF @OBX_FLAG eq @NO

Third, in a copy statement, I check a certain feild for the FLAG condition in a Tcl fragment and if the condition is true, then I set my xlatOutVals to change my @OBX_FLAG to YES.

  COPY  1(0).1(0).1(%g1).OBX.#3  @OBX_FLAG

It seems a bit cumbersome, but it is the only way I could get the IF statement to work and believe me, I tried every way under the sun.  If anyone has any other suggestions, please let me know.

Thanks…

Thomas,

Thanks for your reply . I thought my solution was working but I determined later on the results were not consistent .

I tried your solution and I believe it is much better.

Thanks again for your technique.

Hopefully I can remember it for the next time.

Paul
