PSIONICS FILE - COUNTRY.FMT

Format of Country information files

===================================

The ROM:: filing system contains files which hold localization data.
These files have names like SYS$CTRY.~01, where the number is the locale code
(the built-in language file, English on my machine, is SYS$CTRY.CFO).

These files appear to have the following format (note that the first 40
bytes have the same format as used by system call Fn $8B Sub $05):
  Offset   0 (word): country code (e.g. UK is 44) of locale
  Offset   2 (word): current offset from GMT in minutes (+ is ahead)
  Offset   4 (byte): date format (0 = MDY, 1 = DMY, 2 = YMD)
  Offset   5 (byte): time format (0 = am-pm, 1 = 24 hour)
  Offset   6 (byte): currency symbol position (0 = before, 1 = after)
  Offset   7 (byte): currency symbol separated with space (0 = yes, 1 = no)
  Offset   8 (byte): currency decimal places
  Offset   9 (byte): currency negative format (0 = minus, 1 = brackets)
  Offset  10 (byte): currency separate thousands
                     (0 = no, 1 = yes, 4 = 10000 and over)
  Offset  11 (byte): thousands separator
  Offset  12 (byte): decimal separator
  Offset  13 (byte): date separator
  Offset  14 (byte): time separator
  Offset  15 (cstr): currency symbol
  Offset  24 (byte): start of week (0 = Mon, 1 = Tue, ... 6 = Sun)
  Offset  25 (byte): summer times: 2 = European, 4 = Northern, 8 = Southern
  Offset  26 (byte): clock type (0 = analogue, 1 = digital)
  Offset  27 (byte): number of letters in day abbreviation (0 to 6)
  Offset  28 (byte): number of letters in month abbreviation (0 to 255)
  Offset  29 (byte): workdays (the set bits indicate the workdays)
    Bit 0: Monday
    Bit 1: Tuesday
    Bit 2: Wednesday
    Bit 3: Thursday
    Bit 4: Friday
    Bit 5: Saturday
    Bit 6: Sunday
    Bit 7: unused, always zero
  Offset  30 (byte): units (0 = inches, 1 = centimetres)
  Offset  31 to  39: unknown, always zero
  Offset  40 (word): locale code
  Offset  42 (cstr): suffix for ordinal 1 ("st" in English)
  Offset  45 (cstr): suffix for ordinal 2 ("nd" in English)
  ...
  Offset 132 (cstr): suffix for ordinal 31 ("st" in English)
  Offset 135 (cstr): suffix for 12-hour clock times before midday
  Offset 138 (cstr): suffix for 12-hour clock times after midday
  Offset 141 to 396: character type table - entry i describes character i:
    Bit 0: set if an uppercase letter
    Bit 1: set if a lowercase letter
    Bit 2: set if a decimal digit
    Bit 3: set if a cursor movement code
    Bit 4: set if an other graphic character
    Bit 5: set if a control code
    Bit 6: set if a hexadecimal digit
    Bit 7: space
  Offset  397 to  652: table to convert to uppercase
  Offset  653 to  908: table to convert to lowercase
  Offset  909 to 1164: table to fold character (see below)
  Offset 1165 to 1996: unknown [looks like a table of words]

Starting at offset 1997 are 5 message tables:
  Application errors
  OPL errors
  I/O errors
  OS errors
  System messages
Each table has the format:
  Offset  0 (word): number of first message in the table (F)
  Offset  1 (byte): number of last message in the table (L)
  Offset  2 (word): offset in the file of the next table
  Offset 4 onwards consists of (L - F + 1) qstrs.

Folding characters (offset 909) converts the character to a form which omits
accents and case; by convention (but not required) folded characters are always
uppercase.
