comment
procedure hyph is called when a hyphenation of a
line is wanted.
depending on the value of the global variable
hypmode the information is taken either from procedure
breakpt or from procedure breakpt and the console or
from the backing store. (see description of hypmode).
the value of hyph points at the element in array a after
which the break should be made.
procedure breakpt has the same parameters as
procedure hyph and contains an algorithm for finding
a natural breakpoint or a hyphenation point.
in case that an english text is to be processed
the corresponding procedure ebreakpt for english
hyphenation will be called.
the following possibilities are examined in the
mentioned sequence:
1. a natural breakpoint i.e. a point after
a punktuation character (p.ex.,:) or a
natural terminator (p.ex + -)).
2. a pair of consonants which can not be
pronounced.
3. a consonant between two vowels
4. two consonants between two vowels.
parameters:
a a boolean array, each element containing a character
of the line to be hyphenated or breaked.
composed characters will have the format:
<character><1-unit backspaces><character>
<1-unit backspaces>....<1-unit spaces>
each element contained in one element
of a.
n1 an integer pointing at an element of the
first character of the actual string (word)
in a.
n2 an integer pointing at an element of the
first character after which a break or
hyphenation may be made
n3 an integer pointing at an element of the
last character before which a break or
hyphenation may be made.
n4 an integer pointing at an element of the last
character of the actual string (word).
global variables:
language an integer denoting the language
of the actual text: 1 for danish
and 2 for english.
linelim. an integer denoting the upper limit
of the array a which should be declared
a(1:linelim).
hypmode an integer selecting the way of furnishing
the hyphenation information.
hypmode=1 the procedure prints on the console a
proposal of hyphenation (made by call of
procedure breakpt) which the user can
accept by typing + or reject by typing
- and the correct position of hyphenation.
the hyphenation - information is stored in
zone hyphinf.
hypmode=2 like hypmode=1 but the information is
not stored.
hypmode=3 the hyphenation - information is read
from zone hypheninf
hypmode=4 the hyphenation - information is taken
from the procedure breakpt without
communication with the user.

pair an integer one dimensional array containing a
tabel denoting the pairs of consonants which
can be pronaunced together before the vowel
in a syllable.
the vertical entrance corresponding to the
index of pair denotes the left consonant and
the horizontal entrance corresponding to the
bit number of the elements in pair denote the
right consonant.
a bit=1 denotes that the pair can be pronounced.
