The Automatic Proofreader
The Automatic Proofreader by Charles Brannon is a series of checksum utilities published by COMPUTE! Publications for its COMPUTE! and COMPUTE!'s Gazette magazines and various books. These programs allow home computer users to detect errors when entering BASIC type-in programs. They display a checksum for each line which can be compared against the one printed in the magazine.
It was initially published for use with the Commodore 64 and VIC-20 but was later made available for the Atari 8-bit computers, Apple II, IBM PC, and IBM PCjr.
C16/Plus4 compatiblity was added in issue 32 of COMPUTE!'s Gazette and removed after issue 78.
The first version used a byte-sized numeric value. The later Atari and Apple versions used two letters.
The New Automatic Proofreader introduced in 1986 was designed to run on any 8-bit Commodore (including the C16, Plus/4 and C128) and replaced the decimal display with two letters, could catch transposition errors and took spaces into account if they were within quotes.
