Oh. I though he wanted the file text parsed into tags:values. E.g. if
the file text was something like:

parameter1 3.14159
threshold2 2.71828

then the resulting structure (using IDL definition) would look something
like

text = {parameter1 : 3.14159, $
threshold2 : 2.71828}

and then, via something like:

text = read_myfile("readme.txt")

you could then do

btstruc = {mm: momentmm,$
ros: btstruc.ros, $
readme: text}

and then

IDL> help, btstruc.readme
** Structure <df05a8>, 2 tags, length=8, data length=8, refs=3:
PARAMETER1 FLOAT 3.14159
THRESHOLD2 FLOAT 2.71828

But, yes, now I see this may be what he meant (and much simpler).

cheers,

p.s. Some days I always get the answer for "What colour is General
MacArthur's white horse?" wrong.
