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).
