Overview 

Adis provides the run-time support for Screen Section and enhanced
ACCEPT/DISPLAY syntax.  Adis consists of four modules:

Adis                 

                    The main support module.

adisinit            The initialization module, used only when Adis is
                    first loaded.

ADISKEY              

                    The keyboard-handling module.

adisdyna            The Adis dynamic attributes module.

Enhanced ACCEPT/DISPLAY 

The enhanced ACCEPT/DISPLAYsyntax provides functionality beyond the
standard ANSI ACCEPT syntax, which enables you to input a data item or
accept the day, date or time into a data item, and the ANSI DISPLAY
syntax, which enables you to output literals and the contents of data
items.

With the enhanced ACCEPT/DISPLAY syntax supported by Adis, you can
specify screen position and screen attributes.  It also makes it possible
to do either single-field or multiple-field ACCEPT operations.  For
multiple-field ACCEPT operations, FILLER describes the number of
character positions to skip over to the next field.  In a DISPLAY
operation, FILLER defines the number of spaces between literals.  All
areas defined as FILLER are unaffected by the ACCEPT or DISPLAY
operation.

Screen Section 

The Screen Sectionis a section in the Data Divisioncontaining one or more
screen definitions.  A screen definition may contain fields, groups, text
and attributes.  Fields may have edited picture strings and may also have
features such as NO-ECHO, JUSTIFIED RIGHTand BLANKWHEN ZERO. The effect
of ACCEPT and DISPLAY statements on screen definitions is handled by
Adis.

Configuration 

Adis can be configuredto affect the behavior of ACCEPT and DISPLAY
statements at run time.  You can configure Adis in two ways:

   1.  by using its screen configuration utility (Adiscf) to tailor its
       behavior in an application (see the chapter Adis Configuration 
       Utility (Adiscf)).

   2.  by making calls to Adis from the COBOL application at run time.
