Greetings All

1. I'm trying to find a way to get the total amount of values in a

table. I found arraysize but that doesn't seem to give me the correct output

Example: If I create a table with "; arrayx 0 .1 .3 .5 .3 .1" I'm trying to get the output to be 5 since there are 5 values in it.

if you set manually array values, maybe [list-abs/list-len] is the answer...

something like this:

[.1 .3 .5 .3 .1( | [list] | [t a a] | | | [list length] | | | [;arrayx resize $1( | [list prepend 0] | [list trim] | [s arrayx]

2. I'm also trying to set all values in array to zero with out having

to zero each index.

Example If I create a table with "; arrayx 0 .1 .3 .5 .3 .1" is there an option to set all indexes values back to zero (or set the entire array back to zero) without creating another object like this"; arrayx 0 0 0 0 0 0"

[;arrayx const 0(

you are not creating a table with this. what you do is to set the first 5 elements of an existing table, whatever it's length is.

in order to count the elements you just set you could use [list length].

[0 .1 .3 .5 .3 .1( | [list length] | [6
| [- 1] | [5\ <-- tadaa!

if you want to resize a table, use the "resize" message. [resize 19( | [s arrayx]

2. I'm also trying to set all values in array to zero with out having to

zero each index.

use the "const" message.

[const 0( | [s arrayx]
