Default actions IN CONSTRUCT

When an CONSTRUCT instruction executes, the runtime system creates a set of default actions.

According the invoked default action, field validation occurs and different CONSTRUCT control blocks are executed.

This table lists the default actions created for this dialog:

Table 1. Default actions created for the CONSTRUCT dialog
Default action	Description
`accept`	Validates the `CONSTRUCT` dialog (validates field criteria) Creation can be avoided with `ACCEPT` attribute.
`cancel`	Cancels the `CONSTRUCT` dialog (no validation, INT_FLAG is set) Creation can be avoided with `CANCEL` attribute.
`close`	By default, cancels the `CONSTRUCT` dialog (no validation, INT_FLAG is set) Default action view is hidden. See Implementing the close action.
`help`	Shows the help topic defined by the `HELP` clause. Only created when a `HELP` clause is defined.

The accept and cancel default actions can be avoided with the ACCEPT and CANCEL dialog control attributes:

CONSTRUCT BY NAME cond ON field1 ATTRIBUTES (CANCEL=FALSE)
