       The remainder of the bank consists of a table consisting of a series of
       _NWE_TBL word entries:-

   10     _MTBL         Start of first entry.  

 i                      Nth entry starts at i = 10 + (N-1)*entry size

 i+0 1  I _MTBL_RUN          Run number
 i+1 1  I _MTBL_START_DTE    Run start date (format: yyyymmdd).
 i+2 1  I _MTBL_START_HMSC   Run start time (format: hhmmsscc  - cc is centisec)
 i+3 1  I _MTBL_START_50MHZ  Run start 50MHz clock.
