In the HTML part of each section, scraps of Algol 68 code should be
enclosed in exclamation marks (bangs). In this manual, we refer to
such scraps, including the bangs, as snippets.
For example,
you might refer to a mode as !REF INT!
. The part between the
bangs will be formatted as Algol 68 code. In this case, the upper case
characters will be made lower case and font switching HTML code
issued to ensure that the mode is printed in a bold-face
font. Any Algol 68 code, and any amount of code, can be
placed between the bangs, but you should ensure that each such snippet
can fit on a single line of text because the normal formatting
involving new lines will not be used.
