Default actions in DIALOG

According to the sub-dialogs defined in the DIALOG instruction, the runtime system creates a set of default actions. 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.

This table lists the default actions created for the DIALOG interactive instruction, according to the sub-dialogs defined:

Table 1. Default actions created for the DIALOG interactive instruction
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 created if `INPUT ARRAY` is used; action creation can be avoided with `INSERT ROW = FALSE` attribute.
`append`	Appends a new row at the end of the list. Only created if `INPUT ARRAY` is used; action creation can be avoided with `APPEND ROW = FALSE` attribute.
`delete`	Deletes the current row. Only created if `INPUT ARRAY` is used; 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. Only created if `DISPLAY ARRAY` or `INPUT ARRAY` used with a screen record having only one row.
`prevrow`	Moves to the previous row in a list displayed in one row of fields. Only created if `DISPLAY ARRAY` or `INPUT ARRAY` used with a screen record having only one row.
`firstrow`	Moves to the first row in a list displayed in one row of fields. Only created if `DISPLAY ARRAY` or `INPUT ARRAY` used with a screen record having only one row.
`lastrow`	Moves to the last row in a list displayed in one row of fields. Only created if `DISPLAY ARRAY` or `INPUT ARRAY` used with a screen record having only one row.
`find`	Opens the fglfind dialog window to let the user enter a search value, and seeks to the row matching the value. Only created if the context allows built-in find.
`findnext`	Seeks to the next row matching the value entered during the fglfind dialog. 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.* ATTRIBUTE( INSERT ROW=FALSE, APPEND ROW=FALSE, ... )
     ...
