QPOINTERS

Due to the additional overhead of resolving Q to Q pointers which is not normally necessary in a well maintained system,  an environment variable JEDIENABLEQ2Q must be set. The use of Q to Q pointers should be discouraged.

Note: If an ACCOUNT name does not exist in the JEDIFILENAME_SYSTEM when resolving system entries then on UNIX, the ACCOUNT is looked up in the /etc/password file. If successful then the home directory from the /etc/password file is used for SystemEntryAttr2.
