Procedure DatasetMerge(data\_category, dataset[, dialog])

DatasetMerge

The procedure DatasetMerge merges the data of an existing dataset with the current data. You can use it to merge either a dataset that is passed as argument to the procedure, or a dataset that the user can select via a dialog box. Only the non-default data that is stored in the dataset will be merged with the current data.

DatasetMerge(
       data_category, ! (input) element in AllDataCategories
       dataset,       ! (input/output) an element parameter into AllDataSets
       [dialog]       ! (optional) 0 or 1
       )

Arguments

data_category

An element in AllDataCategories, specifying the data category for which a dataset is loaded.

dataset

An element parameter in the set AllDataSets. If the argument dialog is set to 0, then no dialog box is shown and the dataset to which the element parameter currently refers is loaded. If the argument dialog is set to 1, then the value of the element parameter is used to initialize the dialog box. The dataset that the user has selected and is loaded successfully is returned through this argument.

dialog (optional)

An integer value indicating whether or not the user gets a dialog box in which he can select the dataset to load. The default value is 1, thus if this argument is omitted the dialog box will be shown.

Return Value

The procedure returns 1 on success. If the user cancelled the operation, then the procedure returns 0. If any other error occurs then the procedure returns \(-1\) and CurrentErrorMessage will contain a proper error message.

Note

• This function is only applicable if the project option Data_Management_style is set to Single_Data_Manager_file.
