DESCRIPTION

21       ncpdq packs or re-shapes variables in input-file  and  stores  them  in
22       output-file.   Which  variables  to  pack/unpack  are determined by the
23       packing policy encoded in the pck_plc argument to the -P switch.  Valid
24       pck_plc  options  are  all_new, all_xst, xst_new, and upk.  The numeric
25       type of variable to pack or re-pack a variable to is determined by  the
26       packing  map  encoded  in the pck_map argument to the -M switch.  Valid
27       pck_map options are flt_byt, flt_sht, hgh_byt, hgh_sht, and nxt_lsr.
28
29       ncpdq re-shapes variables in input-file by re-ordering and/or reversing
30       dimensions  specified  in  the dimension list.  The dimension list is a
31       comma separated list of dimension names, optionally prefixed  by  nega‐
32       tive signs, that follow the -a switch.  To re-order variables by a sub‐
33       set of their dimensions, specify these dimensions in a  comma-separated
34       list  following  -a,  e.g., -a lon,lat.  To reverse a dimension, prefix
35       its name with a negative sign in the dimension  list,  e.g.,  -a  -lat.
36       Re-ordering  and  reversal  may  be  performed simultaneously, e.g., -a
37       lon,-lat,time,-lev.
38
39       Users may specify any permutation of dimensions, including permutations
40       which  change  the  record dimension identity.  The record dimension is
41       re-ordered like any other dimension.  The record  dimension  is  always
42       the  most slowly varying dimension in a record variable.  The specified
43       re-ordering will fail if it requires creating more than one record  di‐
44       mension amongst all the output variables.

SEE ALSO

64       The full documentation for NCO is maintained as a Texinfo manual called
65       the  NCO Users Guide.  Because NCO is mathematical in nature, the docu‐
66       mentation includes TeX-intensive portions not  viewable  on  character-
67       based  displays.  Hence the only complete and authoritative versions of
68       the NCO Users Guide are the PDF (recommended), DVI, and Postscript ver‐
69       sions  at <http://nco.sf.net/nco.pdf>, <http://nco.sf.net/nco.dvi>, and
70       <http://nco.sf.net/nco.ps>, respectively.  HTML and  XML  versions  are
71       available          at          <http://nco.sf.net/nco.html>         and

79       should  give  you access to the complete manual, except for the TeX-in‐
80       tensive portions.
