Client/server-based Trace Viewer for Print Services Facility

      Disclosed is a client/server-based trace viewer for Print
Services Facility (PSF) product running in the MVS environment.  The
client operates in a desktop OS/2* to view, format, note, and tailor
traces in the host (server).  Reference Fig. 1 for an overview of the
tool.

Following is the PSF trace viewer end-to-end flow:
  o  User enters an OS/2 command to view the target trace file:
       PCHOS2 psfview.ext (trace file name)
  o  The command invokes a PCHOS2 script (psfview.ext) to run a host
      REXX program to (1) abstract key events of the host trace file,
      (2) build an indexed file, (3) download the file.  PCHOS2 is an
      OS/2 command processor which supports controlling host sessions
      (TSO, ISPF, CICS, IMS...) from OS/2.
  o  The OS/2 main program displays the indexed file to allow the
user
      to browse and search for events of interest.

    In the example, each trace entry is prefixed with an index and
suffixed with a time stamp.
  o  The user points and clicks on selected fields in the indexed
file
      (e.g., control block name) to trigger downloading of additional
      trace data.  Reference Fig. 2 for the client/server
communication
