Word Worker v1.0 by Jim Garrick - Don't have much information about this simple word processor written in BASIC for the Commodore 64.  I found this on a floppy disk called Comtec #1075.  It appears from this Lemon64 post that Comtec might have been a distributor or shareware / public domain software.

Word Writer by Green Valley Publishing is a straight forward line based text editor for the Commodore 64.

WORD WRITER 4 is a complete writing environment for memos, manuscripts and everything in between.  It provides all the tools necessary for organizing your thoughts before you turn them into text plus everything you need to edit, insert, delete(remove) and rearrange your text. You'll produce professional looking documents that reflect your writing style, using either your printer's built-in text mode features or using WW4's premium-quality fonts.

Note:  Had trouble getting this to work in VICE 3.1.  Works fine in CCS64 v3.9.2 and on the Ultimate64.

Wordcraft 64 is an older word processing program for the Commodore 64 which appears to have come on the scene in 1983 when it was adapted by Nick Hickman.  Although it's not super fancy, it does support RS232 printing.

Written by Jim Garrick. Wordmaster isn't quite a word processor but close. If you want to quickly edit or create and Seq. file, this is a good choice. Fully menu driven and very easy to use.

WRITE NOW! 64 (1983) by Computer:Applications Inc (Distributed by CARDCO, Inc.).  Described by the manual as follows:

WRITE NOW! was designed to provide you with an easy to use inexpensive word processor that provides the most desired features of an expensive word processor while being simple to learn and efficient to use. WRITE NOW! is written completely in machine language to eliminate the slowness found in some word processors. WRITE NOW! also uses screen oriented editing so it does not require the cumbersome editing modes required by other word processors.

As far as I know, the program was only officially distributed in cartridge form, but a group called ABA-Soft created a disk version.  This archive contains both a .CRT and .D64 if the program.  The .CRT version was pulled from a ROMset found here on archive.org, and the .D64 version was found here on csdb.dk. The manual for WRITE NOW! 64 can be found here.
