The file is composed of two parts - the first section is the format of the ASCII file, the second, the format of the binary file. The ASCII format file *.af must be renamed to *.afm to be used with the Freeform utility. Likewise, the binary format file *.bf must be renamed to *.bfm. The structure of this file is: Field 1: Variable name Field 2: First position of variable in line Field 3: Last position of variable in line Field 4: Type of variable Field 5: Precision of variable **Refer to Freeform user's manual for further information See format file dnag.fmt in this directory ==================================== ======================================================== Sample Data A representative sample of data records showing the first 10 lines and the last 10 lines of the ASCII data file(i.e. the .dat file).
