Hi Christophe,
thanks for the answer, that's exactly what I was looking for.
I've tried to use the Visible parameter before but could not figure out how to
implement it but yesterday the penny finally dropped :-)
Regards,
Marco
PS: If someone is interested below is an example of how you could do it
// Set the number of maximum dielectric
groups//============================================nr_dielectric_groups_max
=10;
// Check the number of dielectric group variables present in ONELAB database//
If there is none no action is taken// old_nr_dg represent the nr. of dielect.
groups available from previous script
run//==================================================================================old_nr_dg=0;For
i In {1:nr_dielectric_groups_max} seekZero = GetNumber(Sprintf(" Dielectric
parameters/ Dielectric thickness %g", i)); If (seekZero!=0) old_nr_dg +=1;
EndIfEndFor
// Define the new nr. of dielect.
groups//======================================DefineConstant[
nr_dielectric_groups = {1, Min 1, Max nr_dielectric_groups_max, Step 1, Name "
Dielectric parameters/Nr. of dielectric groups"} ];
// Chose which variables will be
hidden/shown//===========================================If
(old_nr_dg>=nr_dielectric_groups) nr_count=old_nr_dg;Else
nr_count=nr_dielectric_groups;EndIf
For i In {0:nr_count-1} visi_flag(i)=0;EndForFor i In
{0:nr_dielectric_groups-1} visi_flag(i)=1;EndFor
// Create variables and update menu
view//======================================For i In {0:nr_count-1}
dielectric_thickness(i) = DefineNumber[ 550, Min 1, Max 2000, Step 1, Name
Sprintf(" Dielectric parameters/ Dielectric thickness %g", i+1), Visible
visi_flag(i) ]; dielectric_thickness(i) = dielectric_thickness(i)/1e6;EndFor

You can "undefine" them using "UndefineConstant[]". But in practice we usually
simply hide them (with the "Visible" attribute) : this way if you change your
mind and later re-increase "nr_dielectric_groups", you will still have the
value that you might have selected before.
