1. file limit
Howdy folks,
I have come uppon a problem that I've never noticed before.
I have a program that opens 2 files. While 1 is opened it attempts to
open the other one and fails. I think I am currently using the PD
version of the newest Euphoria interpreter but not sure (how do I
tell?).
Is there a file open restriction on the PD version of Euphoria?
If so, I'll just register but I didnt remember this ever being the case.

If you run ex/exw/exu with no parameters, it displays the version.

No, but the better debug support certainly is useful!
Do you have an example?

Howdy folks,
Ok I can't duplicate the problem in a another (smaller) program.
Opening 2 files at once works fine.
Also on my main program I modified it so that it would not have
both open at the same time and the problem still persists.
I'm sure it's something really obvious and simple in my logic but
I just can't see it.
Basically the error I get is that a file number is -1
which means the file open statement didn't work.
I just cant figure out why!
The path I try to open is assembled by the program from sequences
but I know the path is correct because I wrote it to another file
(which opened fine) then opened that file and copied it to the
command line edit comand and it opened the file fine from edit too.
Any suggestions folks? If I post the whole program it's large and
multiple files and requires Euallegro and some bitmaps and other files.
What could cause an }}}
<eucode>open( path, "r" )</eucode>
{{{
statement to
not work?
help!

What is the exact value of path?
Try print() and puts() (just puts() may be hard to see a
space at the begining or end)

Hi Lewy,
It seems that other program is acessing one of the files or they are not
corrected closed.

Or they are crosslinked on the drive, so opening one locks both. Try running
chkdsk/scandisk. Regardless, i still have problems with Eu apps locking
entire drives, so other apps cannot access them at all, even when no
reading/writing is going on.

Since no one replied directly to the original question.....
Euphoria has a 19 File Handle Limit that can be open at a single
instance. This should be true for both PD and Registered versions. I
would check to make sure the path your passing is correct. make sure no
extra data is being placed where you don't want it.
