FIND_CY2KT (UPX6)

The FIND_CY2KT user exit, UPX6, performs accounting or utility functions when the TPF system retrieves a pool section keypoint table (CY2KT). The FIND_CY2KT user exit also provides a mechanism that allows you to supply your own function to convert CY2KT from its current format to 32-way loosely coupled pool support format or a user-defined format compatible with 32-way loosely coupled pool support format.

The FIND_CY2KT user exit is called by the FIND_CY2KT function from segment CYH6.

Input

EBXSW0
Contains the index of the data level where CY2KT is to be constructed. The index is in the form of data level 0 (D0) to data level F (DF). The specified data level is free on entry to the user exit.

EBXSW3
Contains the ordinal of CY2KT to be converted.

Return Values

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

R6=1
If this value is returned, CYH6 returns to its caller without changing CY2KT. Use this return code if you code this user exit and your code converts CY2KT from its current format to 32-way loosely coupled pool support format or a user-defined format compatible with 32-way loosely coupled pool support format.
