# JRT Pascal – Programming Language

I said that last time we might actually begin writting a program in PASCAL using the JRT PASCAL system for CP/M and the AERCO RP/M disk system. What I am going to do is to actually “walk” you through a demo program, and a very simple one, that will show you what actually takes place when you create your program.
