源代码的PDF程序作为输入文件，由两列…
The pdf program with source code takes as input a file that consists of two columns.
The first column has in capital letters BC, TC, NC. BC indicates that the ascii text will be byte compressed. TC indicates that the text will be text compressed and NC indicates that the text will be numerically compressed.
The second column will have a text string beginning with and ending with quotes. For BC the text must consist of the numbers 0-9 and letters A-F ( Hex 0-9, A-F). Also, in BC if the length of the string is odd,a zero will be prepended to the string to make it and even number.
For TC the text can consist of any of the legal
text compress charactors in the pdf417 standard. For NC, the letters 0-9 are allowed in the text.
