hi all -

i have put a description and some examples together: how to use the new 
arrays in csound6. the description Arrays.txt contains:

- some notes about variables: when to use kArr[], when to use kArr, etc.
- how to create and fill
- how to query the length
- how to copy arrays from / to tables
- math operations on an array
- how to query minimum, maximum, sum
- how to scale an array
- how to slice an array
- how to use an array in a udo

i have attached examples for all of this. most of the examples replace 
the old t-var examples of the manual (they are already in git).

i will be off in some days, for some weeks, so i'd be happy if someone 
could have a look at the text, and put it at any appropriate place. feel 
free to modify in any way. this is certainly just a starting point -- it 
was written because i wanted to know myself how i can use this new 
feature, and to share this knowledge.

thanks a lot to all who made this possible. it will change, and 
simplify, the way of programming and working with csound. and we are 
just at the beginning ...

	joachim

First reading looks correct -- but missing genarray.

yes, because it did not work for me. and now, after reading your reply 
to my first remark, i do not understand the current behaviour of 
genarray at all. why does it change the array at i-time? i cannot see 
the sense in it.

you have maparray and maparray_i. why not to have genarry and 
genarray_i? all the current opcodes, except the ones for creating an 
array (init and fillarray) are k-rate. and changing the content of an 
already existing array - as a whole or partly - during performance (not 
at init-time) is needed, in my opinion.

so, my vote is:
1) to change the current genarray opcode to work at k-rate.
2) to write a genarray_i opcode which could be used similar to fillarray:
   kArr[] genarray_i 1, 5
would create an array of length 5 with content [1, 2, 3, 4, 5].

Hi All,

Just wanted to follow up, it looks like Joachim added these to the git
repo, and Francois added the XML version. Is anyone currently looking
at the arrays.txt file?

Thanks!
steven

i think this might not be the best place. i'd suggest the following:

to rename the "Function Table Control" section to "Function Table 
Control and Arrays", and to put it at the end of this section.

what do others think?
