Statscraft 0.7.0, release v0.7.0

UPDATE

Replace values of a primary file with the values of transaction files, by key.

Syntax

UPDATE FILE=* | 'path' | dataset [/RENAME=(old = new) ...] [/IN=var]
       /FILE=... [/RENAME=...] [/IN=var] [/FILE=...] /BY varlist
       [/MAP] [/KEEP=varlist] [/DROP=varlist].
The first FILE is the primary file, which may hold each key once; the others are
transactions. Every file must be sorted by the keys. A transaction value replaces the value
of the case with its key unless it is system-missing, user-missing or blank; transactions
apply in order, case by case and file by file. A key only a transaction has adds a case, a
variable only a transaction has adds a variable. Dictionaries combine as in MATCH FILES.
IN adds a variable at the end, 1 for the cases that file holds, else 0 (F1.0); KEEP and
DROP cannot name it. MAP lists the variables at that point with their names in each file.
There is no FIRST or LAST, since every key gives one case. The weight and the documents
follow MATCH FILES. FILE=* cannot follow TEMPORARY.

Example

UPDATE FILE='customers.sav' /FILE='changes.sav' /IN=changed /BY id.
