COBEC0044W CSA option returns NULL - Non-portable usage

The EXEC CICS ADDRESS CSA option will always return a null pointer/address value in the emulation. This option is a non-portable usage due to its dependence on the specific format of internal CICS control blocks.
System Action:
The command and option are processed normally and a WARNING message is issued. The emulation will return a null pointer (or address) value in the argument specified for the CSA option; any reference to data areas using this address may cause unpredictable results.
Resolution:
It is recommended that the CSA option be removed. Access to standard CICS system information should be acquired using the EXEC CICS ASSIGN command or using the CICS System Programming API commands.
