FILE_CY2KT (UPX7)

The FILE_CY2KT user exit, UPX7, performs accounting or utility functions when the TPF system files a pool section keypoint table (CY2KT). The FILE_CY2KT user exit also provides a mechanism that allows you to supply your own function to convert CY2KT from its current format to pool expansion (PXP) format or to a user-defined format that is compatible with PXP format.

The FILE_CY2KT user exit is called by the FILE_CY2KT function from segment CYH6.

Input

EBXSW0
Contains the index of the data level where CY2KT is to be filed. The index is in the form of data level 0 (D0) to data level F (DF).

CY2KT is in 32-way loosely coupled pool support format or a user-defined format compatible with 32-way loosely coupled pool support format.

Return Values

R6=0
Default return code. If this value is returned, CYH6 converts CY2KT from 32-way loosely coupled pool support format back to PXP format and moves CY2KT into keypoint 9 (CTK9). Use this return code if you code this user exit and do not change CY2KT.

R6=1
If this value is returned, CYH6 does not change CY2KT or copy it to CTK9. Use this return code if you code this user exit to convert CT2KT to PXP format or a user-defined format compatible with PXP format. Your user exit code must move the converted CY2KT to the appropriate fields in CTK9 and file CTK9 to DASD.
