I found these opcodes, functions, and operators that are apparently not
mentioned in the manual. Some of these may be only aliases for other opcodes,
or used only internally by the parser, or are documented somewhere I did not
notice. Nevertheless, this list is probably worth having a look at, to find
out if any of the following need to be documented:

chani
chano
cogoto
delayk
event_i
exitnow
FLgroup_end
FLpack_end
FLpanel_end
FLscroll_end
FLtabs_end
loopsegp
lpsholdp
oscilv
OSCsend
puts
pvsinit
seqtime2
sprintf
sprintfk
strcat
strcatk
strcmp
strcmpk
strcpy
strcpyk
strget
tab

I think OSCsend is the only one of those which is mine.  Will try to
add a manual section.  I did have some responsibility for the bit-wise
logical operations.  I assume they should be described like the other
arithmetic operations.

I will lokk at OSCsend, &, |, #, ~

Did I do << and >> ?  Do not sound familiar

No, I added << and >> for binary shift left/right. Here is a list of
available bitwise operators:

  a & b   AND
  a | b   OR
  a # b   XOR
   ~a     NOT
   ¬a     NOT
  a << b  shift left
  a >> b  shift right

The order of precedence (defined in express.c) is, from highest to lowest:

   - (unary)
   ~ ¬
   ^
   * / %
   + -
   << >>
   &
   #
   |
   < <= == >= > !=
   &&
   ||
   ? :

operators on the same line have the same precedence, and (I assume) are evaluated
from left to right.
Note: possible bug: combining unary operators as shown below does not work:
   -(~0)    should be 1 but is syntax error
this is OK however:
   ~-1      correctly evaluates to 0

Are << >> logical or arithmetic?

They round the arguments to the nearest integer and then perform the
C operation << or >>.

According to an old C book of mine, the right shift operator can be either
arithmetic or logical when applied to a signed integer depending on the
machine/compiler.

So this might not be portable.

Well, then I can replace it to be calculated as

   a / (1 << b)

instead of

   a >> b

...and can depend on word length

But C programmers have been using dangerous operations for decades.

Well, I have changed ugmoss.c to use

   input1 / (1L << input2)

instead of

   input1 >> input2

Of course, this is slower, but makes it sure that for example -16 >> 2 is
always -4, and not some large positive value that depends on sizeof(long).

Is there a WYSIWYG editor for xml mamual files?
