How can I use a another variable as part of the name of a new variable?

I want to be able to change two variable names to change the naming of multiple variables. For example. Participant_Number = P1; Intensity = High; I want to be able to change Participant_Number and Intensity to change the name of a new variable. So the result would be: New_Variable would be named P1_High_NewVariable

Is this possible?

"Is this possible?"

Possible, yes. Good way to write code, no.

Magically accessing variable names is one way that some beginners force themselves into writing slow, complex, buggy code that it hard to debug. Read this to know why:

It is possible, but only by ignoring the advice given here and here.
