摘要
PL/M 是一种先进的结构式高级系统程序设计语言。在系统程序设计中使用PL/M高级语言代替汇编语言将导致方案开发期间的高度生产率,这意味着为用户显著降低原始软件开发和后来维护的成本。作为一种系统实现语言,PL/M 的运行不需要任何操作系统或运行支持系统等环境,这种可以裸机运行的特点不仅节约了存储器,而且使这种语言可以适用于大多数微处理器。本文详细叙述笔者所做的一系列关于PL/M 语言在多种CPU 环境下的可移植性试验及其研究结果。
PL/M is an advanced,structured,high-level programming language.
The use of PL/M high-level language for system programming,instead of assembly
language,results in high productivity for project development.It reduces the corts
for both initial software development and followed maintenance signficantly.
As a system-implementation language (SIL),PL/M a bare-machine programm-
ing language,not only saves memory,and does not need any overhead for oprating
system or run-time system,but also is suitable for most microprocessors.This paper
mainly introduces the portability of PL/M.
