1. gets() question
I'm trying to read in the name of several movies, one on each line, to a
sequence. gets() seems to be reading only the first character. Here's the
code:
object tempMovies
integer numMovies
sequence movieNames
movieNames = {}
for i = 1 to numMovies do
tempMovies = gets(filenum)
movieNames = movieNames & tempMovies
end for
????

This example is obviously incomplete but it is the correct way to read the
movie names from a file (where each movie name is on it's own line) and put
them into a sequence. (Note: that the names in the sequence will all have
a linefeed ('\n') at the end.) But the question is: How are you
determining that it is only reading the first character. If you are
printing the contents of the sequence using printf, then note the following
from the reference manual:
Comments: Watch out for the following common mistake:
name="John Smith"
printf(1, "%s", name) -- error!
This will print only the first character, J, of name, as each element of
name is taken to be a separate value to be formatted. You must say this
instead:
name="John Smith"
printf(1, "%s", {name}) -- correct
Now, the third argument of printf() is a one-element sequence containing
the item to be formatted.
Hope this answered your question...

You're adding to your movies sequence like a string. This would work better:
movieNames &= {tempMovies}
or
moveNames = append(movieNames,tempMovies)
Don't worry - you're in good company. I do that from time to time
