Editing ADABAS (section)

====Programs====
Natural objects are identified by names up to 8 characters, the first of which must be alphabetical.

The Natural program editor allows source in rows of up to 72 positions.  Lines are numbered by 4 digits. This numbering is generated by Natural during program creation.  Line numbers used by the compiler and editors, and can have important logical functions in the programs.

Comments can be included in two ways:

* Full-line comments are identified by a "*" or "**" prefix.
* Annotated code lines have a "/*" - everything to its right is a comment.

Examples:
 0010 * These two lines (0010 and 0020)
 0020 ** are comments.
 0030 FORMAT LS = 80 /* As well as this part of the line (0030)
 0040 * NOTE: The "/*" form has no space between the SLASH and ASTERISK.

 0200 END
"END" or "." indicates the end of a program.

A Hello World code example:

 * Hello World in NATURAL
 WRITE 'Hello World!'
 END
