last issue of Antic was June–July 1990. All told, 88 issues and a "Best of" book were published. TYPO A utility called TYPO ("Type Your Program Once," a play on typographical error) was used to verify that programs were typed in correctly that generated set of check-sums for different portions of the lines of code, but it didn't help users find exactly which line had the error. TYPO was later succeeded by TYPO II, a smaller, faster program that generates a checksum two letter code for each Atari BASIC line entered in a program. By comparing each line's checksum with that printed in the magazine, the reader could be sure they typed the BASIC source correctly before entering the next line of code. Versions of TYPO were also published and used (with permission) by Page 6 magazine. ANALOG magazine also used a two-letter checksum code for their type-in programs they offered and was interoperable with Antic's TYPO II.
