set_gaps_missing

Set_gaps_missing uses the same scanning method as show_coverage
to find contiguous sections of absent records in a slotted or integer
prime-key dataseries.  For the range specified set_gaps_missing will
generate records with all default values except if there is a QUALITY
keyword it will be set to 0x8000000 and if there is a DATAVALS it will
be set to 0.

QUALITY must be an int, else DATAVALS will be used.

Command line
  ds={seriesname}
  low=<first prime value to examine>
  high=<last prime value to examine>
  {key=<primekeyname>}
  {<other_primekey=value>}...
  -i  print index values vs prime key values in table
  -q  omit header information

The program operates as follows:

1.  get prime key list and determine name and type of index to use.
2.  get any other prime keys to use to filter the results.
3.  Read existing file or create new empty list.
4.  Scan target series from low to high limits and categorize each record
as OK, Missing, or unknown.
5.  Create records of MISSING for slots with no records matching the
    prime_keys specified.
5.  Write report coverage map, as header and table
first rows of header contain:
series=<seriesname>
key=<primekeyname> - user name, not slotted index name
type=<slotted type, or variable type, e.g. int or short or longlong>
step=<value of keyname_step>
epoch=<epoch>
low=<table first value
high=table high value.
end -- marke end of header

next print coverage table, 3 words per line
kind start length
where kind is:
    OK - data is present for this range
    MISS - data is all known to be permanently missing for this range.
    SETMISSING - data was absent but is now set to MISSING

start is in user units
length is count of recordscontiguous 

List terminates with line containing
