Is it possible to declare and use variables in lnav scripts (not env vars)?

You can use a SQL SELECT statement to set variables, like so:

;SELECT 1 AS one, 'two' AS two

And, then reference then in commands that support variable substitution, like :echo:

:echo $one and $two

Some commands do not perform substitutions, so you need to use :eval.

You can also reference the variables in subsequent SQL statements:

;SELECT $one, $two
