Brief reminders

Very little of what has been said in this handbook needs always to be remembered. The things which are vital are

• The equations corresponding to the various functions
• Meanings of magnetic instructions
• The content of PERM
• The normal use of pages
• Teleprinter equivalents
• Essentials of the input routine
• Some knowledge of conventions

An attempt has been made to condense all this information on two sides of a sheet of paper. Naturally in such a form it needs much interpretation, and all the difficult parts are unrepresented. The equations are given in the most abbreviated form, and sometimes rather ambiguously. The input programme is represented by a number of examples which should be enough to remind the reader who has been through the section on this subject. See Fig.G [which is two pages in the manuscript, but three in this transcription].
