sequence tyme -- can't use the word 'time' as a var.
tyme = gets(0)
if find(':',tyme) = 2 then tyme = '0' & tyme -- look for colon position
end if
puts(1,tyme)

2. Entering Time Values
Irv,
My tyme sequence in effect would be:
{"1","0",":","3","0"} if I enter the tyme as 10:30. But date[4..5] =3D
{10,30}. How do I compare the two?
As you can see, tyme is just digits, while date() are thetrue values. I
can't even use &. In Euphoria, can I combine two atoms of a sequence int=
o
one atom?

I believe that the routine you should be looking at is value().
include get.e
sequence value_return
integer hour, minutes
value_return = value(tyme[1..2])
hour = value[2] -- hour is now 10
value_return = value(tyme[4..5])
minutes = value[2] -- minutes is now 30
value() checks if a string can be converted into a value, and returns a two
element sequence, the first element tells if it was succesful, and the
second gives the number it found. (Maybe lousy explenation, but I hope you
see what I mean)
And here is the compare:
If compare({hour,minutes},date[4..5]) = 0 then -- if no difference
-- woohoo, they match!
end if
Hope I did not say anything wrong now... No code is tested.

Einar,
You did fine. I'm going out now, but your code makes sense. Boy, there =
is
nothing Euphoria cannot do!

Einar I looked all over for that routine when I was writing the internet
starter that is on my webpage. I finally gave up on a built in conversion
and wrote one that changed time values from Date into actual time elements.

6. Re: Entering Time Values
Alan, try filtering tyme through this before comparing:
tyme={value(tyme[1..2]),value(tyme[4..5])}
tyme={tyme[1][2],tyme[2][2]}

oops, the problems already been solved. That's what I get for posting
before I finish reading all my mail.
8. Re: Entering Time Values
Here's another way to do what you want:
sequence now
sequence lunchtime
now = date()
now = sprintf("%02d:%02d"&10,now[4..5])
puts(1,"The current time is: "&now)
puts(1,"What time would you like to eat? ")
lunchtime = gets(0)
if find(':',lunchtime) = 2 then
lunchtime = '0' & lunchtime
end if
if compare(now,lunchtime) = 0 then
puts(1,"Let's Eat!")
else puts(1,"OK, wait until "&lunchtime)
end if
Regards,
Irv
