The Change QHST Version  command creates a new version of  a QHST file.
The intent  of the tool is to  allow you to run the  command at the end
of  some time  period where  you want to  back up  complete versions of
QHST such as all  for the previous month  and start a new time  period.

You must have *ALLOBJ authority to use CHGQHST.

The command has no parameters and would be entered as:

             CHGQHST

A new QHST file would be created by the system.

Two messages are sent to QHST.

  **   TAA1031 is  sent to describe why  the QHST file  is being ended.
       Depending  on  the system  activity  of messages  being  sent to
       QHST, this may not be the last entry in the log.

  **   TAA1032 is sent to ensure that  a new log is forced.   Depending
       on the  system activity  of messages  being sent  to QHST,  this
       may not be the first entry in the log.
