Indirection

Names can also be stored in ordinary text files. Indirection through a text file is indicated by the character.

$^\wedge$ (tophat)

The names may include wildcards (for images) and other indirections (up to 7 deep). A typical response might be:

IN > ^rflatfields.lis

And the rflatfields.lis file would contain something like:

ffr1
ffr4
ffr10
rflats/*

Indirection can be mixed with other specifications in response to a prompt (or on the command line) i.e.:

IN > *,^otherframes,elsewhere/r*

etc.
