Kartik,

the DCNLDN decoder is designed against the data being sent on the IDD
from SUNY-Albany.

If you have ascii data, you can put the data into a text format 
as SFLIST outputs, using latitude and longitude as data,
and thenimport by creating the file with SFCFIL and importing with SFEDIT.

An example of creating a ship format file from ascii text is shown at:
http://www.unidata.ucar.edu/cgi-bin/msgout?/glimpse/gempak/4406

A sample of ascii format for SFEDIT might look like:

 PARM = SLAT;SLON;SGNL;MULT
