Using HolonJ

Installation 

• Store the unzipped files in one common directory, say C:\HOLONJ. 
• Incude the HolonJ directory in the PATH statement in AUTOEXEC.BAT.

HolonJ works best with the Java 2 SDK V1.2 or a later version. No adjustments are needed for HolonJ. 

Note: HolonJ creates class files on its own. You need the Java SDK for the execution of your applications. If you only create applets, the SDK is not actually needed - but it is helpful.

Starting HolonJ

HolonJ runs under DOS. When HOLONJ.EXE starts, it looks for the files HOLONJ.STR and HOLONJ.TEX in the working directory. For details see the file WELCOME.HTM in the HolonJ distribution. 

Toolbox

The three toolbox modules are present in every project.

• _Compiler, defines the Java compiler words.
• _Library, collects the imported Java library classes, methods and fields.
• _Forth, contains the standard Forth words.

Application

Every application module defines one class, usually. 

Load All 

Initially the full system is loaded, and HolonJ generates a class file for every class. 

• Press Ctrl+F3=LoadAll to load the system. 

Load Module

Now only the modules that are changed need to be (re)loaded. 

• Press F3=Load to reload the current module. The corresponding classfile is replaced. 

Testing

The class files are tested in the Java interpreter in the conventional way, or interactively in HolonJ with the monitor JMON
