auxiliary strings

[tvonbrasch]

Hi,

I would like to create an auxiliary string %theta1 that I can use in other string operations, i.e.,

Code: Select all

%theta1 = "(exp(tau1))"
%theta4 =  "2*{%theta1}"


how can I make the string %theta4 so that it becomes

Code: Select all

%theta4 = "2*(exp(tau1))"

by using %theta1?

Code: Select all

%theta4 = "2*" + %theta1 + ")"
