Field help (ACTPARAM6) 

Possibility to add a process before and/or after an Object, Inquiry, Standard process, Entry window template, when this action is placed in the contextual menu for a field. This makes it possible to prepare a context (for example assign the variable GCONSULT) before executing an action and/or starting by example, a display after the action.

The "before" action code is the name of the label preceded by A. The "after" action code is the name of the label preceded with B.

Example : if the action is linked to the button 2 of the field CHP, the before and after labels will be AB2_CHP and BB2_CHP. It must be programmed in the $ACTION label of the standard or specific/custom process.
