COMMENTS:
An uninitialized name provided to the enqc call causes the
address 0 to be used as the address of the name. This did not
cause any run time errors with CDC but it could if another
program also used the address 0 for any reason.
 

SOLUTION:
The cdc_lock which is passed in the ENQ_NAME parameter to the
enqc function has been initialized to "IBM_CDCI". This will
satisfy the documented requirements of the enqc function and
guarantee that CDC uses a unique lock.
 
COREQS:
None.
 

MIGRATION CONSIDERATIONS:
None.
