CSV-COPY

Generates a formatted list of attributes and copies them to a Reality CSV file created with the MAKE-SPECIAL command.

Syntax

CSV-COPY file-specifier {item-list} {selection-criteria} {USING file-specifier} {output-specification} {format-specification} {macro-call}

Refer to The English Sentence for details of parameters.

Prompt

The following prompt is displayed:

DESTINATION FILE:

You must enter a file specifier specifying the Reality CSV file where the new items should be written. If the file you specify is not a CSV file, an error message is displayed.

Restrictions

Normally SYSMAN account only, but can be used in another account if copied into its MD. To have the command added automatically to new accounts, add it to the USER data section of the NEWAC file.

Operation

When you use CSV-COPY, each selected item becomes an item in the CSV file, with attributes as specified in output-specification. These items are given numeric item-ids, starting at one and increasing by one for each subsequent item.

Caution

Existing items with the same item-ids are overwritten.

A heading item is also created with item-id 0, containing one attribute for each attribute in the output specification. Each attribute of this heading item contains the text from attribute 3 of the corresponding data definition item, if any, from the source file; where there is no data definition item, the attribute is left blank. In addition, a data definition item is created in the dictionary of the CSV file for each field, in the same way as for MAKE-SPECIAL.

If you omit the explicit output specification, you must specify a macro that generates an implicit output specification. The default macro is not run automatically.

Example

:LIST UNION '355' '222' '483' LAST-NAME CITY COUNTRY
