How to use javascript objects system.record and system.oldrecord

[dvtssm]

In a script, I need to make reference to a field (change form) in the current record and in the previous record(equivalent of the $file0 in the format control).
I found objects javascript system.record and system.olrecord. How do they work and how to make reference to my field in these two objects?
Thank you for your help.
Regards.

the record and oldrecord objects replace $file and $file0. so you can actually use record and oldrecord the same way you would use $file or any other file object in JS. Check the trigger 'contextAction.post.update' for an example.

Great !! Thanks for your reply :-))
FI, this trigger exists on SM 7.11 and not on 7.02 (the version I'm working on).

in that case check one of the globallists triggers for examples
