This manual is a reference manual which describes the Atlas Autocode Compiler currently available (1/3/65) at Manchester University. It is not a teaching manual though we have tried to make it fairly readable. Further compilers may in the future become available both on Atlas and other machines and it is expected that they will be described with reference to this manual.
We would like to thank Mr. G. Riding for his many valuable comments and suggestions and Miss Christina O'Brien who has typed and re-typed the manuscript.

The copy of the manual used to create these pages originally belonged to N. K. Ganguly.
Like the Atlas Algol dialect, Atlas Autocode programs were normally produced using a Flexowriter with backspace capabilities allowing some characters to be produced using one or two overstrikes. For example:
≤ ≥ ≠ ≡ ;
Where suitable Unicode characters can be found to replace these, the Unicode characters have been used. Where no Unicode character is available, striking though or underlining is used to create a similar character.
The original document made frequent references to page numbers which are inappropriate to a web document. These have been replaced where suitable alternatives are available.
