Reference in Xlate to variable that doesn’t exist – not generating error

[Jeff Dinsmore]

I mistyped a variable name in an xlate and Cloverleaf doesn’t complain.

I load a variable (@isAthena) with a boolean flag from a Tcl snippet.

I then attempt to reference that variable in an if.

if @isAthen eq =1

Note that the variable is missing the “a” at the end.

I’d expect it to throw a “variable doesn’t exist” error or something, but Cloverleaf doesn’t complain at all – it just evaluates it as not true and carries on.

Is this behavior normal/expected?

As @ variables are dynamic temp variables, I would not expect the engine to complain or throw any warning.  So, I believe this is expected behavior (no error).

What is the “Error:” setting set to on the copy or if command?  If it is set to “Skip”, then you’re correct, it won’t stop with an error.  If it is set to “Error”, you will get a “Fetch failure on ‘<variable name'” error and the process will stop.

Thanks, Paul.  I think that’s the explanation.

The “if” error handling was set to “skip”.

Defaulting to “skip” is a little optimistic.  I’m thinking a better, more conservative, default would be “error”.

Is the default behavior configurable?

Jeff,

When set to ‘Error’ this is what I see in the testing tool:

Fetch failure on <name of variable here, sans @>.

This is one of the reasons I mostly use the temp variable pull down inside the Xlate (non of my keypads function properly :-)).

I don’t believe the Xlate Error Action default action is configurable.
