43 * ebcdic -> ascii 32V conv=oldascii
44 * ascii -> ebcdic 32V conv=oldebcdic
45 * ascii -> ibm ebcdic 32V conv=oldibm

47 * ebcdic -> ascii POSIX/S5 conv=ascii
48 * ascii -> ebcdic POSIX/S5 conv=ebcdic
49 * ascii -> ibm ebcdic POSIX/S5 conv=ibm
50 *
51 * Other tables are built from these if multiple conversions are being
52 * done.
53 *
54 * Tables used for conversions to/from IBM and EBCDIC to support an extension
55 * to POSIX P1003.2/D11. The tables referencing POSIX contain data extracted
56 * from tables 4-3 and 4-4 in P1003.2/Draft 11. The historic tables were
57 * constructed by running against a file with all possible byte values.
