$cinst variables deletion

[Andreas Pfeiffer]

Hi Martin,

Do not prefix an instance variable with „$cinst“. Than it should be save to use the command to remove unused variables.

Best,

Andreas

Hi Andreas,

Thank you for your reply. I have changed how I reference instances to align with your guide. Though I learnt this technique from your sample library where you prefix instances with “$cinst.” in the table classes to reference the rows in the window instance.

Kind regards,

Martin.

Martin,

Yes – when your code is inside the table class you can refer to that same instance using $cinst. For example: $cinst.name refers to the name column of your row or list variable if your code is inside that table class.

But when you want to refer to the instance variable outside of that table class, i.e. from within the form, I would recommend not to prefix the instance variable. For example:

$cinst.iDataRow.name ## would certainly refer to the name column within iDataRow but you lose the tokenisation of that variable. It is better to omit $cinst for this matter.

The same is true for task variables. Some people prefix a task variable with $ctask which is also not a good idea for the same reason.

Hope this explanation helps.

Best,

Andreas
