A location in Chill is an object which can contain values.
A value of a location is generally accessed by the (declared) name of the location. The output conforms to the specification of values in Chill programs. How values are specified is the topic of the next section, section Values and their Operations.
The pseudo-location RESULT (or result) can be used to
display or change the result of a currently-active procedure:
set result := EXPR
This does the same as the Chill action RESULT EXPR (which
is not available in ).
Values of reference mode locations are printed by PTR(<hex
value>) in case of a free reference mode, and by (REF <reference
mode>) (<hex-value>) in case of a bound reference. <hex value>
represents the address where the reference points to. To access the
value of the location referenced by the pointer, use the dereference
operator `->'.
Values of procedure mode locations are displayed by
{ PROC
(<argument modes> ) <return mode> } <address> <name of procedure
location>
<argument modes> is a list of modes according to the parameter
specification of the procedure and <address> shows the address of
the entry point.
Substructures of string mode-, array mode- or structure mode-values (e.g. array slices, fields of structure locations) are accessed using certain operations which are described in the next section, section Values and their Operations.
A location value may be interpreted as having a different mode using the
location conversion. This mode conversion is written as <mode
name>(<location>). The user has to consider that the sizes of the modes
have to be equal otherwise an error occurs. Furthermore, no range
checking of the location against the destination mode is performed, and
therefore the result can be quite confusing.
