I propose a prefix (e. g. %) which causes the variable or other expression after it to be evaluated when the command is issued, so that the definition in which it occurs will contain the current value of the expression and it will not be dependent on the variable (or variables in the expression). E. g.
- b=%a
would create a copy of a and make b a free object with the same value,
- r=%(random())
would give a random value to r which will not change in the future and
- b=%(b+a)
would increment the value of b (a free object) by a.
This would be useful for simple users to copy a variable and it would be necessary for the scripting system I propose.
I like this idea 
Being able to save/copy by value would give powerful new options ... especially using and exploring 'semi-random' constructions and/or IterationList tools, sequences and loops ...
Question: what is the difference to CopyFreeObject()
SetValue(b,a)
SetVaue(r,random())
SetValue(b,b+a)
If a and b are segments, and I use:
How I get b as a full free object? (now I get a dependent object in the algebraic view, Sort by Dependency)
¿what circular definition? possible with script but we need the elements used in it
you can share the file and say the new element with circular definition
Instead of the segments, I needed the distance between two points, so I made a single change in the definitions. With the distance value, I could solve the circular definition.Thanks for your help.
