there are opcodes in the manual that are missing good, simple and/or complete examples. Sometimes there are just plain bugs and the opcodes do not work as they should. This makes that these opcodes seems like black boxes and make them unusable.
I think an example should clarify immediately why at the time it was necessary to create this particular opcode. Without this, knowledge about it can get lost.
If someone knows of an example for an opcode that has been placed in the list below, please let me know.

These are my guidelines for the examples in the manual. They should:
- work right-out-of-the-box.
- run in realtime if possible
- have sr = 44100 (preferably)
- be simple and clear in the purpose of the particular opcode

I work my way through the manual from A -Z and hope that soon this blog can be deleted because all opcodes will have their examples in the manual and my work is done :)

This is the list with unsolved problems with examples:

A
- aresonk......no example, so when to use?
- atonek.......no example, so when to use?

C
- cpspch.......my output = 439.963 and not 440. This should be changed in the manual
- ctrl14, ctrl21....no example, together with initc14,21

D
- delayk.......no example, when to use?
- doppler2.....no example
- duserrnd.....no example

F
- ficlose.......no example,when to use

- hvs2.csd.....what is function of second box?
- hvs2-2.csd...what is function of second box?

I
- imageopcodes...using the examples produces a slightly distorted picture output, uses a .png (image.png) that does not exist.
test1.png and test2.png do exist however
- in, in32, inch, inh, ino, inq, ins, inx, inz....no example
- init.........no examples
- initc14,21...no examples, together with ctrl14, 21

- invalue/outvalue......no simple example that works yet

J
- jacko.csd....can not test yet

L
- linenr.......no example (soundfont ex?)
- lineto.......no clear example yet
- loop_ge, loop_gt, loop_le,loop_lt.......no example
- Loris opcodes....get only zeros as output, Loris 1.7 is being re-investigated by Csound maintainers
- loscilx......plays 16 channel samples but not all is clear. what is iwsize and istrt?
- lposcil......something is wrong, bug is filed
- lpsholdp.....no example
- Linar Algebra opcodes do work but are not yet of great use as they are now.
- LPC..........not very stable opcodes (lpslot)

M
- mac, maca....no example, when to use
- mandel.......no example
- mclock.......no example and cannot verify
- midic14, 21..no examples
- midion2, midiout......sends no noteoff messages, note hangs
- midipolyaftertouch cannot check, no example
- mp3in........has a small bug, to be solved
- midiremot, midglobal.......cannot verify but confirm soundfonts work
- mirror.......no example

N
- noteoff, noteon....no example
- ntrpol.......no example, when to use?
O
- oscil1, oscil1i....no example
- osciln.......no example
- OSCopcode....cannot test atm
- outletk, outletf....no example
- outiat, outipat, outipb, outipc, outkat, outkc, outkc14, outkpat, outkpb......no example, will fight with them later :)

P
- p5g, p5gdata.......cannot test
- partikkel...boring ex
- partikkelsync..zie partrikkel_softsync
- pchbend.....acts weird
- pchmidinn...no examnple
- pconvolve...no ex
- polyaft.....example not clear
- pop, pop_f.........no ex
- port.......no ex
- printf........no ex
- product....no ex
- pset.....no ex
- puts, push, push_f....no ex
- pvsdemix.....no ex
- pvsdisp..........not work
- pvsfread......no ex, something is wrong with pvx generation and the no of channels
- pvsinit, pvsin....no ex
- pvsmix.........no ex
- pvsout.........no ex
- pvstencil........no ex
- pvsvoc.........no ex
- python opcodes......no ex

R
- readk2,3,4.........no ex
- relaese........no ex
- remoteport.......no ex
- remove...no ex
- resonk.......no ex
- resonx, resonxk.....no ex
- resony....how are the parallel filters organised?
- rewindscore....no ex
- rigoto, rireturn.....no ex
- rms..weird ex

S
SF2 opcodes
- sfinstr(3)(m).........what is the difference between sfplay and sfinstr?
- sfpreset, sfpassign.....do not get it
- sliderKAWAI....cannot test - but who can these days?
- stack..........when does one use this?

T
- tonek.........no example

U
- unirand.........i get different output: instr1: i1=0.815, instr2: i2=0,030

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

I'm testing with:
- windowsXP, Csound5.11 and WinXound
- Ubuntu10.04 and QuteCsound.

I think there are real problems with:
- LPC
in my opinion a new set of new and streaming opcodes would be welcome
- FluidAllOut
i do noy get it to work

Again, if you know how to use one of the opcodes above, create a working example and post it here. It will then be added to the manual.
