The program compares two files, two areas in core, or a
file and an area in core. Depending on the way input is
specified the comparison is done integer by integer or
textline by textline. On the latter the input files, of
course has to be textfiles.
When two unequal integers are met they are both printed
(preceeded by an relative address in a way) given by the
format specied in the parameterlist.
When two uneuqal lines are met they are both printed in the
textform, the first preceeded by an asterix '*' and the
second preceeded by an exclamation point '!'. If only one
input source is specified the program works like the
fp-utility program print.
Call:

(<file>=)0 compare <input> (<plist>)0
<file> is a backing store area, a file descriptor, or a
nonempty note.
<input>::= <source>!<source>.<source>!<text>.<text>.text
<source>::= <addr>!<file>
<text> is a <file> only containing texts.
<addr> is an address in corestore.

<i> is an unsigned integer, which is measured in lines when
the input source is <text>.<text>.text, otherwise in
bytes.
<n> is an unsigned integer.
The abbrevations m, r and w may be used instead of max,
relative and words.
Every line printed is preceed by an address (line number)
definning the word (line) treated relative to the beginning
of the source. Normally the address is given in bytes, but
by means of the parameters cw and co the address is given
in words and in octets, respectively.

The standard initial values are:
---------------------------------
<plist>::= text integer code m.10000.4 r.0.0 w.1
This means that every integer is, when printed, treated as
a text string, a signed integer, and as a machine instruc-
tion.
Parameter explanation.
---------------------
binary
prints a word in binary form, i.e. one '1' for the
bit set, otherwise a point.
bits.<frac>
prints a word in unsigned fractions given by
<frac>.bits.1 is equal to binary.
bytes
prints a word as two signed 12 bits integers.
integer
prints a word as a signed integer.
text
prints a word as a string consisting of 3 charac-
ters.
real
prints two words as a signed real.
long
prints two words as a signed long.
code
prints a word as a machine instruction.
max.<i1>.<i2>
<i1> specifies the maximum number of bytes (lines),
which should be investigated.
<i2> specifies the maximum number of bytes (lines),
which may be unequal. If only one source parameter
is specified this parameter need not be declared.
When either <i1> or <i2> is exceeded the program
terminates.
relative.<i1>.<i2>
The number of lines or bytes which should be
skipped before the comparison starts. If only one
source parameter is specified then <i2> need not be
declared.
add.<i>!sub.<i>
The specified constant is added/subtracted from the
relative printed byte, word, or octet number. The
parameter has only effect, when one source parame-
ter is specified.
\f
3
words.<n>
<n> specifies the number of words to be printed on
every line.
cw
the relative printed address is in words.
co
the relative printed address is in octets.
Alarms from running program:
---------------------------
After an alarm the run is terminated.
***compare hard error on <doc>
status <bits>
A hard error has occured on the document doc. The
status word is shown in a binary format.
***compare lookup <doc> result <i>
The document <doc> cannot be connected. The result
of the monitor procedure lookup is shown.
***compare no source
The parameterlist contains no input source.
***compare not a normal text <doc>
A line consist of more than 768 characters.
Warnings from running program:
-----------------------------
***compare param no <i>
A syntax error in the parameterlist is detected.
The parameter-no is shown.
References outside core is not checked and gives a break
0.
When the program stops and the involved files has been
identical it prints:
EQUAL <number of bytes or lines>.
