1. Greetings!
Greetings,
I've been a registered user of EU for sometime and up-till-now I have'nt done
much with it. All that has changed as the creative bug has hit me and have
decided to write an RPG BBS Door game in EU.
I've been a 'lurker' on this list for about a year now. What has prompted me to
start a project with EU is some of the messages about UNFINISHED projects and
such. I decided it was about time for me to START a project <<G> and hopefully
finish it.
I used to program in a language called GFA-Basic, a language for the ATARI ST
(680xx), it is procedure oriented similar to EU, but that was in the 80's and I
really have'nt programmed AT ALL for the Intel chip.
With the above in mind I will become your worst pest in the question department
, forwarned is forarmed. <<G>
Here is a snippet of code that I keep getting an error:
invalid escape character
File = "c:\euphoria\telenora\dorinfo1.def"
^
(I think the EU is interpreting the backslash as part of a 'token' like \n for a
new line...)
as soon as move dorinfo1.def into the BIN directory and change it to read like
this:
File = "dorinfo1.def"
sequence Line,
File,
BBSUserInfo,
UserAliasFirst,
UserRealFirst,
UserAliasLast,
UserRealLast,
PlayerBBSName,
BBSName,
Temp1,
Temp2,
ComPort
-- Initialize Variables
File = "c:\euphoria\telenora\dorinfo1.def"
...
procedure GetDorinfo() -- Gets info from Dorinfo1.def & puts it in
-- the sequence BBSUserInfo.
FileNumber = open(File,"r")
if FileNumber = -1 then
puts(SCREEN,"**** Program Halted ****\nCould Not open " & File
abort(1)
else
for x = 1 to 12 do
Line = gets(FileNumber)
BBSUserInfo = append(BBSUserInfo,Line)
end for
end if
close(FileNumber)
end procedure
-------
Any help would be appreciated....

You don't need to worry about the chip, Euphoria hides all that from you.
What you want to know is the following:
Euphoria preprocesses your code and then it makes an internal form out
of it, when it is doing that, all the escape characters are replaced by real
characters.
An escape character in Euphoria starts like this: '\' and then has a
some character behind it to tell him what character.
Example : '\n' is equal to 13
Which makes the puts routine jump to the beginning of the next line (and
scroll the screen if needed)
But what when you actually want to say '\' as a character ?
Well you use this escape character '\\'
So your file should be:
File = "c:\\euphoria\\telenora\\dorinfo1.def"
Remember that this only goes for your code, when you prompt a user for a
file name, he cannot use escape characters at all. They are there because
for example a line feed with interfere with the linefeeds used to give your
program some structure)
For more information see the documentation (refman,doc), it has to be
there somewhere..
