The "while" syntax is roughly:
WHILE ~ DO ~ OD
or more fully:
FOR i FROM start TO stop BY step WHILE condition DO clause OD
The "case" syntax - for the 4 choices of 'n' from 1,2,3,4 - is:
CASE n IN ~,~,~,~ OUT ~ ESAC or in brief: ( n | ~,~,~,~ | ~ )
or as a compound choice of n & o:
CASE n IN ~,~,~,~ OUSE o IN ~,~,~,~ ESAC or in brief: ( n | ~,~,~,~
|: o | ~,~,~,~ | ~ )
Oddly Algol 68 does not have nested comments like:
CO ~ OC
Rather comments and pragmas are:
CO ~ CO and PR ~ PR
However Algol68C lets programmers code in some "reverent" assembler
code blocks:
CODE ~ EDOC
