static  unsigned char
        ASCII_translate_EBCDIC [file*c_file] =
            {
            0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08,

Just open the file and read it one character at a time, passing each character to that function.

void foo()
{
    ifstream in("filename.txt");
    ofstream out("newfilename.txt");
    char c;
    while( in >> c )
    {
       out << EBCDIC_translate_ASCII[c];
    }
}
