Why storing variables inside a variable?

+0
−4

In the past I have read about the fact that some programmers use a variable to hold two or more variables (instead holding a mere value or an array).
There might also be cases when programmers use a variable to hold just one other variable.

What could be a good typical simple example for the need in this practice in programming in general? What is a typical problem to solve with this?

I’m not familiar with the expression “compound variable”. Logic suggests it may apply to a programming artifact with multiple named fields (as a struct in c or a record in pascal) or a possibly heterogeneous ordered structure (like a list s-expr or a python tuple), but it might help if you could give more context.

I vaguely recall I have learned about that term a few years back in relation to JavaScript but going through some Google results for "compound variable" javascript I found only different informal definitions, nothing from MDN. I should edit to remove it.
