1. explain it to me
Could someone explain why I can't reassign a sequence like this
rec = "123.45"
rec = value(rec)
rec = rec[2] -- why can't I redefine rec this way if I don't
want the 1st element (or any
others but the 2nd). It's awfully
inconvinent to have to go
through a temp var
everytime.
And I would have thought that the following syntax would have also been
allowed
rec = value(rec)[2] -- this is valid in Theos Basic and seems
logical to me here also. It saves going through a temp var also.

A sequence can't hold an atom, which is what you are trying to do by
assigning rec[2] to rec.
If you make rec an object, then you can do what you propose.

Brian, doesn't value() return { x , y }, where x is the success variable and
y is the actual value?

CK Lester's solution is fine, but I prefer not to declare object variables
unless absolutely nessecary.
I do this..
rec=value(rec)
rec={rec[2]}
this also works....
rec=rec[2..2]
then there is no need for an object variable..

I'd vote for this one..
It has been asked for numerous times..

George,
I almost never remember all the good stuff people put here, so I made a
email folder "code examples" that I copy the best of the best to, for future
reference. Only problem is when people write email subjects like "explain
it to me", instead of something which includes the *nature* of the desired
help, which throws off my ability to easily browse through that folder by
subjects to retrieve something of interest ;)

10. Re: explain it to me
Dan:
I find that the inconsistant subject lines are more commn than on topic
subject lines. So what I've done is set up a 2nd E-mail account on
yahoo that no 1 knows about except me. When I want to save something I
just fwd the message with an appropriate title to that E-mail acct. &
then download that into a similar special folder (like the 1 you
described). Anything that wasn't sent by me is automatically trashed
by Yahoo.
