aren't global arrays possible?

It get an error on this attempt to use a global array.
Is it not possible to use a global array in a function?
Is there another way to use the interpolation in a function?

/A_table = [
[ 0, 0.01h_tip],
[0.1, 0.12h_tip],
[0.2, 0.24h_tip],
[0.3, 0.28h_tip],
[0.4, 0.32h_tip],
[0.5, 0.4h_tip],
[0.6, 0.45h_tip],
[0.7, 0.52h_tip],
[0.8, 0.64h_tip],
[0.9, 0.77h_tip],
[1,1*h_tip]
];
B_table = nSpline(A_table,1000);

function tip(procent) =
B_table[round(procent*10)][1]*h_tip;/

Should work, what error message? (I have not looked at nSpline)

From your script it is quite clear the unknown variable is 'h_tip', it
isn't defined, but used.

Also the function nSpline is undefined as written.

This works for me

use <splines.scad>
h_tip=1;
A_table = [
[ 0, 0.01h_tip],
[0.1, 0.12h_tip],
[0.2, 0.24h_tip],
[0.3, 0.28h_tip],
[0.4, 0.32h_tip],
[0.5, 0.4h_tip],
[0.6, 0.45h_tip],
[0.7, 0.52h_tip],
[0.8, 0.64h_tip],
[0.9, 0.77h_tip],
[1,1h_tip]
];
echo(A_table=A_table);
B_table = nSpline(A_table,1000);
echo(B_table=B_table);
function tip(procent) =
B_table[round(procent10)][1]*h_tip;

I suspect a typo in your code?

Strange, when I paste your codes in an empty file, there is not problem.
When I paste the code on the top of file with modules and functions it
reports errors:

/Saved backup file: C:/Users/Eigenaar/Documents/OpenSCAD/backups/mouthpiece
outside v12-backup-gqHp6640.scad
Compiling design (CSG Tree generation)...
WARNING: Ignoring unknown variable 'B_table'.
WARNING: Ignoring unknown variable 'B_table'.
ECHO: "lchamber", 39, 45.7074, 2.4, 45.7666, 15.6531
ECHO: "chamber", 6.00436, 6.10407, 2.9133, 5.76755, 17.0867, 15.6531,

But it computes the tables and echoes them as expected.

This is one thing about OpenScad that troubles users in debugging. See the
following and refer to my  earlier post
http://forum.openscad.org/Ignoring-unknown-variable-issue-tp13156p13321.html
for more detailed explanation:

whenever you see :

WARNING: Ignoring unknown variable X

It could be one of the following two conditions :

  1. A=X but X is not defined in any place prior to that line,
    means the issue is on X;

  2. A=X but A is already defined prior to that line, before
    X is defined.

In case 1), the issue is on X, but in 2), A is the problem.

So besides checking if X is pre-defined, remember to also
check if A is pre-defined.
