This document contains a list of all keywords that are reserved in the Natural programming language.
Important:
To avoid any naming conflicts, you are strongly recommended not
to use Natural reserved keywords as names for variables.
The following topics are covered:
The following list is an overview of Natural reserved keywords and is for general information only. In case of doubt, use the keyword check function of the compiler.

There is a subset of Natural keywords which, when used as names for
variables, would be ambiguous. These are in particular keywords which identify
Natural statements (ADD, FIND, etc.) or system
functions (ABS, SUM, etc.). If you use such a keyword
as the name of a variable, you cannot use this variable in the context of
optional operands (with CALLNAT, WRITE, etc.).
Example:
DEFINE DATA LOCAL 1 ADD (A10) END-DEFINE CALLNAT 'MYSUB' ADD 4 /* ADD is regarded as ADD statement END
To check variable names in a Natural object against such Natural reserved keywords, you can use one of the following facilities:
The following table contains a list of Natural reserved keywords that
are checked by
KCHECK.
| A - D | E - F | G - P | R - S | T - W |
|---|---|---|---|---|
|
ABS |
EJECT |
GET |
READ |
TAN |
By default, no keyword check is performed.
