Syntax
where B and F are the names of bases or elements
We use the SCAN: command to quantify quickly a limited number of
assessments of adjustments and partial adjustments. There are three
possible scenarios, corresponding to the numbering in the syntax above:
(1) scanning the affect of a basic adjustment; (2) scanning the effect
of a partial adjustment; and (3) scanning the effect of a withdrawal of
sources of information from an adjustment. The fourth form of the
syntax, identical in effect to the equivalent ADJUST: form,
is included for completeness only, and can be used to prepare a base for
adjustment; such preparation is described in detail in
§9.1.4.
Generally, use of the SCAN: command does not affect the current
operator (if any), and will not define one.
As far as expectation specifications are concerned, only the
current default expectation store is ever referenced; the remainder
are ignored. The default expectation store can be changed by using the
e argument to the CONTROL: command.
