Assembler Programming Under ETOS

This document, Chapter 6 of an ETOS manual, details assembly language programming within the ETOS environment. It covers: - General Introduction: Coding at the machine level, assembler usage (PAL8, SABR, RALF, MACREL), and compatibility considerations between OS/8 and ETOS. - IOT Instructions: Detailed descriptions for terminal IOTs (e.g., KSF, KCC, KRB), extended memory IOTs, card reader IOTs, and line printer IOTs. - System Functions (SYSCAL): Comprehensive documentation for extended system functions, including time-of-day (TOD), sleep functions (W100MS, W1MIN), job status (DATAPK), system information (VERSION), and memory management (CORE). - Usage Examples: Numerous code snippets and sample sequences illustrate how to implement these functions in assembly language.
