Exit use case: please review

["Jacques R. Durand" <JDurand@us.fujitsu.com>]

As I am putting together a set of XTemp examples and use cases, I just want to make sure we have a consensus about the Exit semantics in various cases.

Please review the attached script and its expected output, which should be :

 

>We get here because the exit (1) in subvar only breaks out of the var definition.

>We get here because the exiting from scriplet sub does not escalate beyond it.

>Mainvar: Exit 2

 

Which I believe reflects the agreement we came up with, about Exit not breaking out of Var definitions.

 

But the current prototype returns:

 

>We get here because the exiting from scriplet sub does not escalate beyond it.

>Mainvar: Exit 1

 

As Exit breaks out of var definitions.

 

If we agree on the former interpretation, we’ll need to update the prototype (Chuck:  will you have time to do this update? Else I can work on it then double check with you to make sure I did not break something else)

 

Thanks,

Jacques
