1. How to use file_num = open ( "file", "mode" )
I'm fairly new to programming, and would appreciate someone's advice on how
to write code to achieve this:
1 ask the user to:
a) nominate the drive on which to create a file - eg "C"
b) name the file to be created - eg "entries.dat"
2 create and open that file - "c:\entries.dat" - for output
I'm able to use....
file_num = open ( "c:\\entries.dat", "w" )
.... but only if I specify the details myself!
Thank you
Alex Caracatsanis

here try something like this:
-- untested code
include get.e
atom fn
sequence full_path, drive, file
puts(1, "enter drive letter: ")
drive = gets(0) -- get the drive letter in a sequence
puts(1, "enter file name: ")
file = gets(0) -- get the file name in a sequence
full_path = append( drive, ":\\") -- append the ":\\" to the end of the drive
full_path = append( full_path, file ) -- app the file name to the drive letter
-- and ":\\"
fn = open( full_path, "w" )
-- do your stuff
close(fn)
hope that helps ( or even works! )

No, it does not help, because it does not work!
It takes only about 30 seconds to test it, if it works.
If it does not, it usually takes a bit longer, but it saves you a lot
of embarrassment and you do not confuse the poor newbie even more.
jiri
include get.e
atom fn
sequence full_path, drive, file
puts(1, "Enter drive letter: ")
drive = gets(0) -- get the drive letter in a
sequence
drive = drive[1..1] -- strip newline
puts(1, "\nEnter file name: ")
file = gets(0) -- get the file name in a sequence
file = file[1..length(file)-1] -- strip newline
full_path = drive & ":\\" & file -- concatenate
fn = open( full_path, "w" )
-- do your stuff
close(fn)

hey jiri, its no embarassment. At least i was truthful about it not knowing if
it worked. sorry for not testing it and all ( i know you *HATE* untested code
posters ) but i am running linux at the moments and i still have not bothered
to setup euphoria for linux very well yet.
