No. It's used as printf's "format string" to be used for variable counter

After this, we print the rest of the line as a string.
YES, be aware of the strike through.

[QUOTE]However I cannot understand why we need counter+=NF in this case, as NF should be 16. Can you please explain this logic? [QUOTE]
The counter in fact is a pointer into the file, starting at the zeroth byte, then at the 16th, etc. Thus adding the line length (better: line's byte count) keeps the pointer pointing to the correct file position.

Can we use something else to accomplish this (i.e for loop).
What?

cdtoa [-n] [-s] [-z] [-e] [-E] infilename [-h cixingfile ] [ usagefreqfile ] DEFAULT PATH
/usr/local/bin/cWnn4/cdtoa DESCRIPTION
To convert the binary format of the dictionary to text format, and output to standard output(stdout). infilename is the name of the input binary format dictionary. The output may be piped into a file by using the ">" command. For example, cdtoa dict.dic > dict.u "dict.u" here is the output text format dictionary, while the "dict.dic" is the input binary format dictionary. usagefreqfile may indicate more than one user usage frequency files (for a particular user). These usage frequency information will be reflected in the text format dictionary created. OPTIONS

(Note: default is Pinyin) -e If the Hanzi inside the text dictionary contains characters such as space and tab, they will be compacted to special format. (Default) -E If the Hanzi inside the text dictionary contains characters such as space and tab, they will NOT be compacted to special format. -h cixingfile To specify the Cixing definition file. NOTE
1. The parts in [ ] are options. They may be omitted. 2. The Pinyin and Zhuyin dictionary has the same format. 3. The default conversion result of the text dictionary is in Pinyin. 13 May 1992 CDTOA(1)
