It also provides a toolbox specifically for ILBM graphics files. This allows you to use pictures, brushes, anims and animbrushes from a paint program, or other source, in your programs. JForth also provides tools for animation and presentation such as, blit, wipe, fade in, fade out, etc. Powerful graphics and animation programs can be created using these tools. Local Variables Local variables can simplify the definition of complex words by eliminating much of the stack manipulation.
Local variables are fast self fetching variables that allow reentrant recursive code to be written.
Modules JForth's precompiled modules provide a method for rapidly accessing code that is used during compilation. This includes the Assemblers and Disassembler, and the Amiga include files. These modules are dynamically linked into the dictionary when needed. This way, they do not take up space in your normal dictionary, yet are instantly available. This is handy for compiling code written using other Forth s.
