Break Up 128 by Bob Umfer for the Commodore 128 (80 Columns) is a tool to divide up large .SEQ files.

Browser V1 by Rod Gasson (January 1st, 1995) is a nice tool for viewing various text based documents such as ASCII, PETSCII, ANSI, DAT and even BASIC in colorized format.  Super cool tool, but there is a newer version you can find here.

Browser V2, in its simplest form, can be considered little more than a text reader. However, it does have several features that makes it stand apart from all other CBM text readers, including: * The ability to read HUGE text files and BASIC listings (up to about 16meg) with paging and backscrolling facilities. >>>>> REU is NOT required. <<<< This program is truly amazing! Full docs and features are on the disk. Add this to your tool collection.

File Reader / Printer / Converter by John Crookshank is a program for the Commodore 128 (either 40 or 80 column mode) that uses Machine Language to view and print .SEQ text files.  Not only does it view and print, it can also convert documents formatted for 40 columns into 80 column printouts.  Full docs are included in the archive.

File Slicer 128 for the Commodore 128 (80 Columns) is a super simple / small ML utility for turning a single file into multiple files. Don't forget to use DLOAD in 80 Column mode.

Multi Read-Write-Print 128 for the Commodore 128 is a utility to handle various operations on sequential files.

PAGEBACK128 by Simon Tracy (1989) is a bi-directional file reader for the 80 column Commodore 128.

Most sequential file readers are unidirectional; they work in a forward direction only. Once text has scrolled off the screen, the only way to see it again is to load and read the file frow the beginning a second time. This program makes reading a sequential file work like reading a book by implementing bidirectional commands which permit the user to page backwards as well as forwards within a sequential file. In addition, the program includes versatile printing options which often eliminate the need to reformat files with a word processor prior to printing,

PAGEBACK 128 is written in BASIC 7.0 for the Commodore 128 using FAST Mode and requires an 80 coIumn monitor. The program includes two Machine-language subroutines: one for loading the sequential file to a 62.5K buffer and a second routine which implements the file- reading commands. All user choices are clearly presented on screen and efficiently handled by GETKEY statements or INPUT statements with the most likely choice already printed under the cursor.

Sprint 128 for the Commodore 128 (80 Columns) is a file reader.  It can read both sequential and program files.
