Not quite sure what you are asking for, but I'll give it a shot.

If you are looking for an example of how to interpret and act upon gadget
selections, ftp the file "Spotlite.lha".  It's in the dev/e directory on
the Aminet sites (ftp.wustl.edu is the main site).

If you're trying to change the gadget text, I'm not sure if you can do
that under gadtools (there are several dissappointing limitations on
gagtools gadgets as I've found out over the last few days).  You may have
to use a regular Intuition gadget.  (I could be wrong here.  I've been
messing with BOOPSI gadgets too and I might have mixed them up.  Yet
another sign of old age. B-)

Later,

     Jim

[various stuff]

-> Will E 3.0 have proper float support?

depends on what you call 'proper', but yes, it will have operators
that work on floats etc. in the language.

-> Does anyone have some good example sources that show how to use
-> "|" in E?  The only sample program that uses it is 'ReWriteGfx'
-> and I can't make heads or tails of its use in that program...

"|" was the float convertion operator in <2.1a, and shortly before
release I decided I didn't like floats like this in E, so I removed
the documentation about floats. Not many people know this, but
v2.1 actually has floats implemented, but a bit silly if you ask me.

-> Wish List Addendum...
-> -No size/element limit on constant structures, lists, arrays.. E is a
-> dynamic language, why is there a limit on something so silly?

well, yes [] lists and typed list should be able to get longer in the
future. If you trouble with the current limits just because you want to
have a large amount of data in your program, I might advice to use INT
(as statement) or INCBIN or something similar.

-> -Real keyword/constant checking! I want to be able to start my
-> functions/variables in uppercase if I so desire! (You wouldn't believe the
-> problems this is causing with converting Angband to E!) Anything else is
-> just cheaping out to keep compiler speed. Come on!

This is a false assumption many people have made. Those contrains
were introduced into E because I wanted to enforce a common style of
identifiers to make sources more readable. infact, with techniques like
hashing the compiler uses, the speed difference would not be noticable.

-> pound sand up his arse and go to the C mailing list! }:-/

now come on barry! no cursing on this list :-) Be nice to people!

    60 Ifs? My god man. Why did you not just write up a function to do
it?
(off the top of my head)
PROC exponent(num,pow)
    DEF result=0,a
    FOR a:=0 TO pow
        result:=result*result
    ENDFOR
ENDPROC a
Unless I've totally gone bonkers that should return num^pow. (this really
should be included as an operator in high level languages)

    Hmm.. well, this information does not help when dealing with a
guru. Either post the code, or if you don't want to, email it to me and
I'll take a look at it. Most people's E programming bugs are usually just
misconceptions about how E works, or how some function works. It's
probably something really simple, and thus the hardest kind to spot.

    Haven't played with screen for a while.. I assume you are using
2.0+? If not, well, kiss the 2.0 look goodbye without a lot of work. I'll
lookup how to do it when I get home tonight and post it next time.
