5.39 LDMOD (Additional dynamic load modules)

5.39.1 Function

LMOD provides the capability of defining additional modules that will be loaded by the Hercules Dynamic
Loader. The default search order is within the Hercules directory and in the default DLL search path. Most
systems also support absolute filenames (e.g. names starting with “/” or “.”) in which case the default
search path is not taken. Multiple LDMOD statements may be used.

5.39.3 Parameter

module

A list of modules that are to be loaded by the Hercules Dynamic Loader.

5.39.4 Examples

Example 1:

Instruct Hercules to load the additional module named S37X (S/370 Extension) from the Hercules
directory or the default DLL search path.

LDMOD S37X

5.40 LEGACYSENSEID (SENSE ID CCW (x'E4') feature)

5.40.1 Function

This option specifies whether the SENSE ID CCW (X'E4') will be honoured for the devices that originally
did not support that feature. This includes (but may not be limited to) 3410 and 3420 tape drives, 2311
and 2314 direct access storage devices and 2703 communication controllers. Because those legacy
devices didn't originally support this command, and for compatibility reasons, the default is OFF or
DISABLE.

Specify ON or ENABLE, if your guest operating system needs the Sense ID support to dynamically detect
those devices. Note that most current operating systems will not detect those devices even though Sense
ID is enabled because those devices never supported the Sense ID in the first place. This mainly applies
to custom built or modified versions of guest operating systems that are aware of this specific Hercules
capability.

This is the default.

ON

Specify ON or ENABLE if your guest operating system needs the Sense ID support
to dynamically detect devices that originally did not support that feature.
