This command is used
to open a virtual widget with the list mask for the specified type, that
is used to select records. See also DataView function 'iwf_lis_typ'.
If this command is called without transfer string - i.e. 'select_typ( )' only -, the database search is performed in the mask of the currently activated widget. Calling the 'var' command specifies the variables to be assigned. Without this command only the number of matching records is returned (to the function 'execute'). |
