subsystem_cancel_mode

Specifies whether logical or physical cancels are used for CBL_SUBSYSTEM cancels.

Restriction: These tunables are supported for native COBOL only.

Syntax:

>>-----set subsystem_cancel_mode=--.-0-.-----------><
                                   +-1-+
                                   +-2-+

0	Physical cancels: any program canceled with a CBL_SUBSYSTEM cancel will be freed from memory, making more memory available.
1	Compatibility mode. As Logical cancels mode, except that .dll files or shared objects are physically canceled. This option is present for compatibility with older products.
2	Logical cancels: any program canceled with a CBL_SUBSYSTEM cancel will not be freed from memory. The programs are available to be reused and hence the performance of CALL/CANCEL statements is greatly increased.

Default:	0
IDE equivalent:	NoneUse the Application.config file of the project - right-click the file in Solution Explorer and click Open, then select the Run-time Configuration tab.

As far as your program is concerned, logical and physical cancels behave identically.
