x+2?

As of the latest version, all expressions use 'x' as a variable instead of the parameter name.

x+2 was just an example, OK a stupid one ;)

but I missed that all variables in expressions use x now....I tried it with the list lenght component and that is still working with both, the parameter name and x as a variable.

thank you

Why is this? Woudln't it make sense to keep the same naming convention? Also what if you want to use the value of parameter A in Parameter B ?

Several reasons:

• It's now much easier to copy-paste expressions between parameters with different names.
• When switching from regular names to display full names, expressions keep on working.
• It's no longer a problem that expressions have names which do not adhere to VB naming rules (i.e. starting with a number, having weird characters or containing spaces)
• It's no longer a problem to have an expression name be the same as a constant (such as e, phi or pi)

hello if i want to do the following

1.8 < x < C + Min(A,B), where A and B are known and they can change by slider,

and C is a know value as well.
