Most programming books begin with a program to write a simple phrase to the screen, and that phrase is invariably "Hello World!". This section will lead you through the process of writing your first application, helloworld under EMBOSS. You'll cover the basic elements common to every EMBOSS program and introduce the steps used to create applications.

Some of the examples below use mymeboss (Section 3.2, “Integration and Compilation”), so you must first install and configure this package (see Section 1.2, “Installation of CVS (Developers) Release”). myemboss is a special EMBASSY package and is found in the normal EMBASSY application directory e.g.

/home/auser/emboss/emboss/embassy/myemboss
