Chapter 23 Lists of Features
Key to Notation
The features of the VS COBOL language are listed by dialect in the
following tables. The directive used to turn on the features of each
dialect and the definition of the dialect follow the table name.
Notes:
1. There is no table for ANSI '74 Standard features.
2. There is no table for IBM-MS features as they are the same as
those MS features introduced at language level 1.3.
3. Although the ANSI '85 Standard is treated as one dialect, the
information is presented in three tables to distinguish the levels
of that Standard as this may be found useful.
The entries for each feature in the tables are:
1. The language level at which the feature was introduced
2. Effect of directive on the feature
3. Implementation status of the feature
Language Level of the Feature
The language levels are the same as those listed in Key to Notation in
Chapter 20 .
Effect of Directive on the Feature
No effect.
R Turns on the reserved words the feature needs.*
E Enables the feature**, without changing normal program behavior.
C Enables the feature**, which changes program behavior.
W Changes the syntax; normal syntax is flagged with a warning.
* In the case of the Micro Focus and Microsoft directives, reserved
words are enabled to the level specified in the directive; see the
list of reserved words in your Language Reference.
** Not by turning on reserved words.
Implementation Status of the Feature
(space) Fully implemented.
I Fully implemented, but another directive* (not the
dialect one) enables it.
U Syntax support but no run time support in some
environments.
D Implemented as documentary.
G A group of features.
* See the table Directives for Individual Features in Chapter 22 .
