Which variables to pack/unpack are determined by the packing policy encoded in the .IR pck_plc argument to the .BR \-P switch. Valid .IR pck_plc options are .IR all_new, .IR all_xst, .IR xst_new, and .IR upk. The numeric type of variable to pack or re-pack a variable to is determined by the packing map encoded in the .IR pck_map argument to the .BR \-M switch. Valid .IR pck_map options are .IR flt_byt, .IR flt_sht, .IR hgh_byt, .IR hgh_sht, and .IR nxt_lsr. .B ncpdq re-shapes variables in .I input-file by re-ordering and/or reversing dimensions specified in the dimension list. The dimension list is a comma separated list of dimension names, optionally prefixed by negative signs, that follow the .BR \-a switch. To re-order variables by a subset of their dimensions, specify these dimensions in a comma-separated list following .BR \-a , e.g., .BR "\-a lon,lat". To reverse a dimension, prefix its name with a negative sign in the dimension list, e.g., .BR "\-a \-lat". Re\-ordering and reversal may be performed simultaneously, e.g., .BR "\-a lon,\-lat,time,\-lev". Users may specify any permutation of dimensions, including permutations which change the record dimension identity. The record dimension is re-ordered like any other dimension. The record dimension is always the most slowly varying dimension in a record variable. The specified re-ordering will fail if it requires creating more than one record dimension amongst all the output variables. .\" NB: Append man_end.txt here .\" $Header$ -*-nroff-*- .\" Purpose: Trailer file for common ending to NCO man pages .\" Usage: .\" Append this file to end of NCO man pages immediately after marker .\" that says "Append man_end.txt here" .SH AUTHOR .B NCO manual pages written by Charlie Zender and originally formatted by Brian Mays. .SH "REPORTING BUGS" Report bugs to . .SH COPYRIGHT Copyright \(co 1995-present Charlie Zender .br This is free software; see the source for copying conditions.
