How can i check if a file is open

[okee]

If i do

Code (glbasic) Select Expand

IF OPENFILE(1, WordFile$, 1)
     print "Open",1,1
else
      print "Couldnt open" + WordFile$, 1,10
endif

This tries to open a file and returns a message if it can't
If the file opens succesfully, is there any way later on to
check that the file is open, say something like ISFILEOPEN(1)

You shouldn't really need to check to see if a file is opened later on

However, you could either use a flag variable (set it to TRUE if its open), and set it to FALSE when the file is closed

or

you can use a TRY/CATCH/THROW block

Ok i just thought i'd overlooked a command.
Just on another note is there any reason why you cannot assign
a channel number greater than 7 to a file, while i was debugging
i put in a channel number 8 which caused an error.

Gernot has limited the file handle numbers to between 0 and 7

depends on the environment.  An app wants to open a server based file, one that potentially was opened by another user already, might find it useful to do some checking first

Good point there!  I dont know how Sqlite does it, but Pervasive would set various bytes within the database file to a certain value...
