SCREEN COBOL Features Not
Supported for Web Conversion
Certain SCREEN COBOL features are either not supported for conversion to web
clients or have a modified representation in the converted code. In some cases, this is
because the features are not applicable in a web environment or because of limitations
imposed by Java.
Table B-1
lists the SCREEN COBOL statements and clauses that are not supported or
have limited support for conversion. For each feature, the table explains the action
taken by the converter when it encounters this feature and what you can do to correct the
situation.

SCREEN COBOL
Feature Converter Action
Recommended
Corrective Action
CHECKPOINT Because the web client does not run
with a backup process, this
statement is not meaningful in a web
environment. The converter
generates a warning and continues
converting the rest of the program.
The converted Java code contains
the warning statement as a
comment. The converted code will
compile, but the effect of the
CHECKPOINT statement is not
provided by the converted code.
No corrective action
needed.
DEVICEINFO The converter generates an error and
continues converting the rest of the
program. The converted Java code
contains a non-compilable
statement.
Either remove the non-
compilable statement
from the converted
code or remove the
DEVICEINFO
statement from the
SCREEN COBOL
source program.
DISPLAY RECOVERY,
EXIT RECOVERY
The converter generates a warning
and continues converting the rest of
the program. The converted Java
code contains the warning statement
as a comment. The converted code
will compile, but the effect of the
DISPLAY RECOVERY and EXIT
RECOVERY statements is not
provided by the converted code.
No corrective action
needed.
