use Use read as a prompt inside a while loop driven by read?

I have a usecaseuse case where I need to read in multiple variables at the start of each iteration and read in an input from the user into the loop.

Possible paths to solution which I do not know how to explore --

  1. For assignment use another filehandle instead of stdin

  2. Use a for loop instead of ... | while read ... ... I do not know how to assign multiple variables inside a for loop
