GIGI

This manual describes the GIGI Character Set Editor, an interactive screen editor designed for creating and modifying characters for the GIGI graphics terminal's three programmable alternate character sets. It provides comprehensive usage and reference information for all users, covering both its capabilities and detailed functions.

The document is structured into three main parts:

1. Getting Started: This section introduces the editor's features, capabilities, screen layout, and explains how to invoke it on VAX/VMS, RSTS/E, and TOPS-20 operating systems. It also details how GIGI relates alternate characters to native ASCII characters and handles character display and spacing.
2. Using the Character Set Editor: This part guides users through the various commands and keyboard operations for creating and manipulating characters. It covers both single-character editing and mosaic editing (combining multiple characters), utilizing main keypad commands for overall control and auxiliary keypad functions for direct pixel manipulation (drawing lines, boxes, etc.).
3. Command Descriptions: This section provides detailed, alphabetical descriptions of each Character Set Editor command, including their syntax and options. Commands cover character editing (CLEAR, COPY, EDIT, FONT-NAME), display control (DIMENSION, SHOW CHARACTER, SHOW ALTERNATE, MOSAIC, REDRAW), and file management (READ, WRITE) for loading and saving character sets as REGIS files.

The editor allows users to define new characters or mosaic patterns within an 8x10 dot matrix composition frame, control their appearance (e.g., size, slant, rotation), and manage character set files on host on-line storage.
