This manual describes how to use ga68, the GNU compiler for
Algol 68. This manual is specifically about how to invoke
ga68, as well as its features. For more information about
the Algol 68 language in general, the reader is referred to the
bibliography.
Note that the particular way of representing Algol 68 code snippets in this manual will depend on the media. If you are reading this manual in a printed support or a PDF file rendered for publication then the bold words in programs will be rendered in actual bold typography and tags may have spaces within them. If you are reading this manual in a terminal or other media not supporting rich typography the code examples will follow the modern stropping regime with is the default in ga68.
Note also that we are making use of pseudo-comments in code
examples, as it is traditional in Algol 68 related documentation.
These appear surrounded by C marks and act as placeholders
of some Algol 68 code. For example, C frob the input
variable C is a pseudo-comment.
