NAME
tconv - HP 9000 Traditional-Chinese code converter SYNOPSIS
tconv tconv 1 tconv 1 num infile outfile tconv 1 -n num -f file_of_namelist tconv 2 [-r] [-ps] [-rs number] -m method -i infile -o outfile tconv 3 tconv 3 num infile outfile tconv 3 -n num -f file_of_namelist tconv 4 tconv 4 num infile outfile tconv 4 -n num -f file_of_namelist tconv 5 tconv 5 num infile outfile tconv 5 -n num -f file_of_namelist DESCRIPTION
tconv is a code converter to do code conversion from CCDC/Big5/EUC-CNS(locale: zh_TW.ccdc/zh_TW.big5/zh_TW.eucTW) internal code to another local Taiwanese 2-byte or 3-byte Traditional-Chinese internal code, or to Unicode in UCS2 or UTF8 format; as well the conversion of Big5 code(Traditional-Chinese) to GB code(Simplified-Chinese) (locale:zh_CN.hp15CN) or GBK code. It provides fourteen processing modes. Mode (1) : tconv The first one is an interactive menu mode. Just invoke the command. It will display the main menu, and prompt you for which kind of code conversion you need(whether it is between 2-byte and 2-byte, 3-byte and 2-byte, 4-byte and 2-byte, Traditional-Chinese code and Sim- plified-Chinese code or even Unicode). After you choose, if it's 2-byte and 2-byte, it will display the 2-byte code code conversion sub- menu and prompt you what type of code conversion you need and then ask you your input filename and output filename. If it's 3-byte and 2-byte, it will show the usage of it and ends. If it's 4-byte and 2-byte, it will display the 4-byte code code conversion sub-menu and prompt you what type of code conversion you need and then ask you your input filename and output filename. And then, if it's Traditional- Chinese and Simplified-Chinese, it will display the Traditional-Chinese and Simplified-Chinese code code-conversion sub-menu and prompt you what type of code conversion you need and then ask you your input filename and output filename. Finally, if it is Unicode, it will display the Unicode code conversion sub-menu and prompt you what type of code conversion you need and then ask you your input and output filenames. Mode (2) : tconv 1 The second is also a menu mode. If you invoke the command. It will go directly to the 2-byte code code conversion sub-menu. Mode (3) : tconv 1 num infile outfile The third is used to convert one 2-byte code text file to another code type text file in command mode. The infile stands for the input filename, outfile for output filename. And num is the selection number you can find out from the interactive menu mode. Below is the description of them : num = 1 : From HP Big5 code to IBM 5550 code. 2 : From HP Big5 code to CDC code. 3 : From HP Big5 code to National Standard code. 4 : From HP Big5 code to HP CCDC code. 5 : From HP Big5 code to Shift-Big5 code. 6 : From HP Big5 code to Taipei Computer Association code. 7 : From HP Big5 code to Tien-Lon code. 8 : From HP CCDC code to IBM 5550 code. 9 : From HP CCDC code to ETen code. 10 : From HP CCDC code to National Standard code. 11 : From HP CCDC code to Shift-Big5 code. 12 : From HP CCDC code to Taipei Computer Association code. 13 : From HP CCDC code to HP VECTRA PC code. 14 : From HP CCDC code to 2-byte WANG PC code. 15 : From Tandem internal code to HP CCDC code. 16 : From IBM 5550 code to HP Big5 code. 17 : From CDC code to HP Big5 code. 18 : From National Standard code to HP Big5 code. 19 : From HP CCDC code to HP Big5 code. 20 : From Shift-Big5 code to HP Big5 code. 21 : From Taipei Computer Assocoation code to HP Big5 code. 22 : From Tien-Lon code to HP Big5 code. 23 : From IBM 5550 code to HP CCDC code. 24 : From ETen code to HP CCDC code. 25 : From National Standard code to HP CCDC code. 26 : From Shift-Big5 code to HP CCDC code. 27 : From Taipei Computer Association code to HP CCDC code. 28 : From HP VECTRA PC code to HP CCDC code. 29 : From 2-byte WANG PC code to HP CCDC code. 30 : From HP CCDC code to Tandem internal code. Mode (4) : tconv 1 -n num -f file_of_namelist The fourth is used to convert many files with one tconv 1 command. You have to create a file with all the filenames you want to convert. Let the file name be file_of_namelist , and the format of the file is : <file1> <file2> <file3> . . . <EOF> Then use the command to convert all those files in batch mode. Also, same as Mode (3), num is the selection number you can find from the interactive menu mode. Notice that you can only do one kind of conversion to all the files in file_of_namelist , and there is no output filenames, all the files will be put into original file names which you specify in file_of_namelist. Mode (5) : tconv 2 [-r] [-ps] [-rs number] -m method -i infile -o outfile The fifth is the command tconv 2 , it is for code conversion between WANG's 3-byte internal code and HP's CCDC or Big5 code. It only supports batch mode procssing. Each tconv 2 command will convert one text file. Options Options for tconv 2 are interpreted as follows: -r this option means fixed record length. Default is free format. This option is useful to text file. -rs number this option is used to specify the record size of the file. For example '-rs 80' means that the record size is 80. The range of number is between 0 and 10240. -ps while converting from WANG to CCDC or Big5. Each 3-byte code will be converted to one 2-byte code and one 1-byte space. It implies fixed record length. -m wang_hp convert from WANG's 3-byte code to HP's 2-byte CCDC code -m wang_big5 convert from WANG's 3-byte code to 2-byte Big5 code -m hp_wang convert from HP's 2-byte CCDC code to WANG's 3-byte code -m big5_wang convert from 2-byte Big5 code to WANG's 3-byte code -i infile specify the input text file name -o outfile specify the output text file name Mode (6) : tconv 3 The sixth mode is also a menu mode. If you invoke the tconv 3 command. It will go directly to the 4-byte code code conversion sub- menu. The description is as follow : (1). From 4-byte Extended Unit Code(EUC) to HP Big5 code. (2). From 4-byte Extended Unit Code(EUC) to HP CCDC code. (3). From EUC to New Host Code(Traditional Chinese EBCDIC). (4). From HP Big5 code to 4-byte Extended Unit Code(EUC). (5). From HP CCDC code to 4-byte Extended Unit Code(EUC). (6). From New Host Code(Traditional Chinese EBCDIC) to EUC. Mode (7) : tconv 3 num infile outfile The seventh is used to convert one 4-byte code text file to another code type text file in command mode. The infile stands for the input filename, outfile for output filename. And num is the selection number you can find out from the interactive menu mode. Below is the description of them : num = 1 : From 4-byte Extended Unit Code(EUC) to HP Big5 code. 2 : From 4-byte Extended Unit Code(EUC) to HP CCDC code. 3 : From EUC to New Host Code(Traditional Chinese EBCDIC). 4 : From HP Big5 code to 4-byte Extended Unit Code(EUC). 5 : From HP CCDC code to 4-byte Extended Unit Code(EUC). 6 : From New Host Code(Traditional Chinese EBCDIC) to EUC. Mode (8) : tconv 3 -n num -f file_of_namelist The eighth is used to convert many files with one tconv 3 command. You have to create a file with all the filenames you want to con- vert. Let the file name be file_of_namelist , and the format of the file is : <file1> <file2> <file3> . . . <EOF> Then use the command to convert all those files in batch mode. Also, same as Mode (7), num is the selection number you can find from the interactive menu mode. Notice that you can only do one kind of conversion to all the files in file_of_namelist , and there is no output filenames, all the files will be put into original file names which you specify in file_of_namelist. Mode (9) : tconv 4 The ninth mode is a menu mode too. If you invoke the tconv 4 command. It will go directly to the Traditional-Chinese and Simplified- Chinese code-conversion sub-menu. The description is as follow : (1). From HP Big5 code to HP GB code. (2). From HP Big5 code to GBK code. (3). From HP GB code to HP Big5 code. (4). From GBK code to HP Big5 code. Mode (10) : tconv 4 num infile outfile The tenth is used to convert one Big5 or GB code text file to the other code type text file in command mode.
