I'd like to set the control sequence
\my_cs to the value of some LaTeX3 expression that expands to a control sequence, e.g. to the value of
In other words,
\some_other_control_sequence is an existing control sequence that is set to some value, and I'd like to set
\my_cs to this value, but without writing out the control sequence
\some_other_control_sequence explicitly. How can I do so?
For instance, suppose
\some_other_control_sequence is a global LaTeX3 variable set to the integer
42, and suppose I'm writing a LaTeX3 function, and the name of this variable, namely
some_other_control_sequence is expected to be passed in as the parameter
#1, but I don't know the name of this variable at the time of writing the function. How can I set
\some_other_control_sequence's value, namely
42, inside the function that I'm writing?
