Bug to pass field as a parameter on link to a form

I want to share a fairly old bug, when creating a link for a form that updates the lookup.
I can’t pass the field as parameter.

hi
in applicationinit try with this

[par_codigo]=[par_codigo];

dear [aamartinezz], could you try to reproduce what [quality] says on your version of scriptcase to see if it works? In my version 9.11.017 (13), field option isn’t available.
