device_name_detection

Specifies whether programs can use filenames that are normally reserved for device-names.

Note: Restriction:

These tunables are supported for native COBOL only.

Syntax:

>>-----set device_name_detection=---.-TRUE-.------><  
                                    +-FALSE+

Parameters:

TRUE	The run-time system treats certain predefined names (such as ERR) as device-names.
FALSE	No predefined device-names are used by the run-time system.

Properties:

Default:	TRUE
IDE equivalent:	None

Comments:

When you set device_name_detection=TRUE, the run-time system treats the following as device-names, so they cannot be used as filenames in your programs:

:BB
:CE
:CI
:CO
:LP
AUX
COM<n>
CON
ERR
LPT
LPT<n>
LST
NUL
PRN
PUN
RDR
STDERR
