Default actions created by a DIALOG block

Default actions ease the implementation of the controller by providing expected actions.

The runtime system creates a set of default actions based on the sub-dialogs defined in a (declarative or procedural) DIALOG block. These actions are provided to ease the implementation of the controller. For example, when using an INPUT ARRAY sub-dialog, the dialog instruction will automatically create the insert, append and delete default actions.

Table 1 lists the default actions created for the DIALOG interactive instruction, for each type of sub-dialogs:

Table 1. Default actions created for the DIALOG block
Default action	Control Block execution order
`help`	Shows the help topic defined by the `HELP` clause. Only created when a `HELP` clause or option is defined for the sub-dialog.
`insert`	Inserts a new row before current row. Only for `INPUT ARRAY` dialogs. Action creation can be avoided with `INSERT ROW = FALSE` attribute.
`append`	Appends a new row at the end of the list. Only for `INPUT ARRAY` dialogs. Action creation can be avoided with `APPEND ROW = FALSE` attribute.
`delete`	Deletes the current row. Only for `INPUT ARRAY` dialogs. Action creation can be avoided with `DELETE ROW = FALSE` attribute.
`nextrow`	Moves to the next row in a list displayed in one row of fields. See note (1).
`prevrow`	Moves to the previous row in a list displayed in one row of fields. See note (1).
`firstrow`	Moves to the first row in a list displayed in one row of fields. See note (1).
`lastrow`	Moves to the last row in a list displayed in one row of fields. See note (1).
`find`	Opens the fglfind dialog window to let the user enter a search value, and seeks to the row matching the value. See note (2).
`findnext`	Seeks to the next row matching the value entered during the fglfind dialog. See note (2).

Notes:

The action is only created with a DISPLAY ARRAY or INPUT ARRAY using a screen record bound to a set of form fields in a GRID container, and this set of fields show only a single row of the list. The action is not created when using a screen array bound to a list container such as TABLE, TREE and SCROLLGRID, or to a set of fields in a GRID container, that repeat on several lines to show more than one single row.
The action is only created if the context allows built-in find.

The insert, append and delete default actions can be avoided with dialog control attributes:

INPUT ARRAY arr TO sr.* ATTRIBUTES( INSERT ROW=FALSE, APPEND ROW=FALSE, ... )
     ...
