PXTRACT PROCESSOR CONTROL FILE
------------------------------
CALMET accepts data for a number of precipitation stations in a
single PRECIP.DAT file. These data are obtained in the NCDC TD-3240
format, with either fixed (hourly event records) or variable record
length (daily records of hourly precipitation events). This NCDC format
typically places data for many stations and long periods in a single
file. PXTRACT extracts a subset of stations, for a specific period,
into files for subsequent processing by PMERGE. Each output file
contains the data for a single station.

Input and Output files:
-----------------------
Default Name Type
File Name
------------ ---- ---------
TD3240.DAT input ! PRECDAT =file0001.dat !
PXTRACT.LST output ! RUNLST =pxtract1.lst !
All file names will be converted to lower case if LCFILES = T
Otherwise, if LCFILES = F, file names will be converted to UPPER CASE
(LCFILES) Default: T ! LCFILES = F !
T = lower case
F = UPPER CASE
NOTES: 1) File/path names can be up to 70 characters in length;
2) Output files are named automatically using the state/station
ID (e.g., 412797.DAT for station 412707)
