1. Pascal compiler

There are multiple flavors of Pascal compilers. I downloaded a free open source Pascal compiler for WINDOWS (latest release 2.2.4) and installed it. This is very easy to do.
Please go to the following site for the down load:

Once you downloaded it and installed the Pascal compiler, you will see a Free Pascal IDE icon, FPC icon on the computer screen. Double click the icon and you will see a IDE screen to input your Pascal program. Please study various options on the top of the screen. We will be using FILE EDIT RUN COMPILE options very extensively.

The cursor is always at an insert character position. We can type in any characters we want. Using Edit, we can edit the information we entered just like in any editor.

Once a program is ready we can Compile the instructions we typed for machine language translation or use RUN for compiling and executing the Object(machine language instructions).
