Syntax
where d is a switch; are the names of data-carriers or bases; and L is the name of a
file label.
The first form of the command is used to export data so that they follow
a label. Typically the label will be a string of alphabetic characters
preceded by the symbol `@' (this symbol is used as the prefix recognised
by [B/D] as implying that the remainder of a string is a label name).
The label is output as one line of text. The second form of the command
is identical to the first except that no label is defined, and no label
will be exported.
On successive lines the data are exported, one line per case. For
example, if the names of two data-carriers D1 and D2 are given, and
if each of these has ten observations defined (
and ) then the output will consist of ten rows of
two columns, with the first column corresponding to D1 and so forth.
Where D1, etc., are the names of bases, all the elements possessing
data in the named base are marked for their data to be output. The
latter two forms of the command do not specify the particular names of
data to be exported, and are used as shorthand to mean that all
data-carriers should be exported. See §6.2 for details of
specifying collections for the definition part.
The data-carriers are output according to the ordering convention
of data name, and their ordering in the EXPORT: command line is
irrelevant.
