We have now covered most of Algol 68. All that remains is the
identity relation, the parallel clause, the mode BITS
,
completers, different precisions of numbers and means of accessing
operating system facilities. Most of these are deceptively simple.
The identity relation is used with modes containing multiple
REF
s which take up the greater part of this chapter. The
BITS
mode and the parallel clause are introduced in later
sections. Different numerical precisions and access to operating
system facilities is mainly covered in chapter 12. We start with
access to the machine word.
