52 * There are currently six tables:
53 *
54 * ebcdic -> ascii 32V conv=oldascii
55 * ascii -> ebcdic 32V conv=oldebcdic
56 * ascii -> ibm ebcdic 32V conv=oldibm
57 *
58 * ebcdic -> ascii POSIX/S5 conv=ascii
59 * ascii -> ebcdic POSIX/S5 conv=ebcdic
60 * ascii -> ibm ebcdic POSIX/S5 conv=ibm
61 *
62 * Other tables are built from these if multiple conversions are being
63 * done.
64 *
65 * Tables used for conversions to/from IBM and EBCDIC to support an extension
66 * to POSIX P1003.2/D11. The tables referencing POSIX contain data extracted
67 * from tables 4-3 and 4-4 in P1003.2/Draft 11. The historic tables were
68 * constructed by running against a file with all possible byte values.
69 *
70 * More information can be obtained in "Correspondences of 8-Bit and Hollerith
71 * Codes for Computer Environments-A USASI Tutorial", Communications of the
72 * ACM, Volume 11, Number 11, November 1968, pp. 783-789.
