INTERCAL::Charset::EBCDIC(3pm) User Contributed Perl Documentation INTERCAL::Charset::EBCDIC(3pm) NAME
Charset::EBCDIC - allows to use EBCDIC string constants in ASCII programs (and v.v.) SYNOPSIS
use Charset::EBCDIC 'ascii2abcdic'; my $a = ebcdic2ascii "(EBCDIC text)"; DESCRIPTION
Charset::EBCDIC defines functions to convert between a subset of ASCII and a subset of nonstandard EBCDIC (since there isn't such a thing as a standard EBCDIC we defined our own variant which is guaranteed to be incompatible with all versions of EBCDIC used by IBM hardware - however, when we have chosen a code for a character, we have made sure that at least one - but certainly not all - IBM models used that same code, so the choice cannot be criticised). If you really want to know, several variants of EBCDIC are listed in RFC 1345, which is available from the usual sources. Two functions, ebcdic2ascii and ascii2ebcdic are exportable but not exported by default. They do the obvious thing to their first argument and return the transformed string. EBCDIC CHARACTER TABLE
The following are the characters recognised. The ones shown as 2 letter abbreviations cannot be translated to ASCII (except for the control characters, which do have an ASCII equivalent). + 0 1 2 3 4 5 6 7 8 9 a b c d e f Notes 00 OV TA LF CR OV=overstrike 10 TA=tab 20 LF=linefeed 30 CR=carr-return 40 SP CT . < ( + !

dd - convert and copy a file SYNOPSIS
dd [option=value] ... DESCRIPTION
Dd copies the specified input file to the specified output with possible conversions. The standard input and output are used by default. The input and output block size may be specified to take advantage of raw physical I/O. option values if= input file name; standard input is default of= output file name; standard output is default ibs=n input block size n bytes (default 512) obs=n output block size (default 512) bs=n set both input and output block size, superseding ibs and obs; also, if no conversion is specified, it is particularly effi- cient since no copy need be done cbs=n conversion buffer size skip=n skip n input records before starting copy files=n copy n files from (tape) input seek=n seek n records from beginning of output file before copying count=n copy only n input records conv=ascii convert EBCDIC to ASCII ebcdic convert ASCII to EBCDIC ibm slightly different map of ASCII to EBCDIC lcase map alphabetics to lower case ucase map alphabetics to upper case swab swap every pair of bytes noerror do not stop processing on an error sync pad every input record to ibs ... , ... several comma-separated conversions Where sizes are specified, a number of bytes is expected. A number may end with k, b or w to specify multiplication by 1024, 512, or 2 respectively; a pair of numbers may be separated by x to indicate a product. Cbs is used only if ascii or ebcdic conversion is specified. In the former case cbs characters are placed into the conversion buffer, con- verted to ASCII, and trailing blanks trimmed and new-line added before sending the line to the output. In the latter case ASCII characters are read into the conversion buffer, converted to EBCDIC, and blanks added to make up an output record of size cbs. After completion, dd reports the number of whole and partial input and output blocks. For example, to read an EBCDIC tape blocked ten 80-byte EBCDIC card images per record into the ASCII file x: dd if=/dev/rmt0 of=x ibs=800 cbs=80 conv=ascii,lcase Note the use of raw magtape. Dd is especially suited to I/O on the raw physical devices because it allows reading and writing in arbitrary record sizes. To skip over a file before copying from magnetic tape do (dd of=/dev/null; dd of=x) </dev/rmt0 SEE ALSO

f+p records in(out): numbers of full and partial records read(written) BUGS
The ASCII/EBCDIC conversion tables are taken from the 256 character standard in the CACM Nov, 1968. The `ibm' conversion, while less blessed as a standard, corresponds better to certain IBM print train conventions. There is no universal solution. Newlines are inserted only on conversion to ASCII; padding is done only on conversion to EBCDIC. These should be separate options. DD(1)
