Re: parser error: syntax error....but cannot find it!
This may not fix the problem, but some things I have noticed that I am
uncertain of:
Your function socketsetscrewsizes doesn't appear to be terminated with a
semicolon.
You seem to use size as a variable in the second half of the code (e.g. pd
= pointdiameter(size);) but I can't see where it is assigned.
You have a variable called pointdiameter, and a function called
pointdiameter. Does openscad allow this?
The vector for size==16 has 4 elements ( probably a comma in place of a
decimal point).
In my experience, openscad is not very good at telling you where the error
actually comes from, so perhaps any one of these could be causing it. Or
not.
Cheers,
Will

Subject: [OpenSCAD] parser error: syntax error....but cannot find it!
Hello at the Openscad forum,
trying my first code with a lookup function from a list, and I get a
parser error: syntax error. The problem is that I cannot find what it wants
from me. I copied an existing syntax, but I must be missing something
because that works and mine does not.
A hint with a little explanation would be really appreciated.
$fn=60;
//flat point set screw is according ISO 4026
//cone point set screw is according ISO 4027
//cup point set screw is according ISO 4029
//example
//iso_4026(size=1.6, length=3);
pointdiameter=0;
socket=1;
pitch=2;
//size==X ? [pointdiameter, socket, pitch]:
function socketsetscrewsizes(size)=
size==1.6 ? [0.8 , 0.78 , 0.35]:
size==2 ? [1 , 0.98 , 0.4]:
size==2.5 ? [1.5 , 1.4 , 0.45]:
size==3 ? [2 , 1.66 , 0.5]:
size==4 ? [2.5 , 2.23 , 0.7]:
size==5 ? [3.5 , 2.8 , 0.8]:

before "size"))

}
cylinder(h=size*s, d=s, $fn=6,center=true);

Ok, now I am not sure how to proceed, here as emails or where?
Till now the 2 answers already helped.I had left out a line with default parameters ending in a semi colon. this caused the first error in the line just below it.
I also had a comma where there should have been a point, easy fix but thanks to Will for spotting that one.
Now it proceeds further but I now come indeed at the size as parameter and as function issue.
Back to the drawing board and find a work around. Just wish it would point better at what IS wrong rather than at what is the RESULT of what is wrong.
