Re: How to combine multi ascii files into one file?

Untar/gz all your files

===================================

   diri = "./" ; data directory
   fili = systemfunc("cd "+diri+" ; ls "*.op")

   STA = toint( str_get_cols(fili, 0, 5) )
   XXX = toint( str_get_cols(fili, 7,11) )
   YEAR = toint( str_get_cols(fili,13,16) )

Then you can specify a station number and year

   sta = 543860
   year = 2001

Find the appropriate file

   i = ind(STA.eq.sta .and. YEAR.eq.year)

Read the file's data

   data = asciiread(diri+fili(i), .......)
