The problem here is a man description out of sync with the code.  I get the
result:
north=31.15.00N - illegal latitude

Usage:
 m.dted.extract [-fhqu] input=name output=name header=name
   [north=name] [south=name] [east=name] [west=name]

Flags:
  -f   Read the entire tape in all cases
  -h   Set extraction region based on DTED header values
  -q   Run quietly
  -u   Process an unblocked file (not a tape)

Parameters:
   input   Name of tape drive device
  output   Name of output file
  header   Name of header output file
   north   North latitude of region to extract (format: dd:mm:ss{N|wr
   south   South latitude of region to extract (format: dd:mm:ss{N|S})
    east   ame]
    west   

This help IS broken, but look closely at the : symbols in the format.  When I
run this command with colons substituted for the periods, it attempts to
execute.  Be sure to set the current region to encompass the area for which
data is being read.
