I think it's something along those lines, but I don't think it's trying
to stick the entire contents of the file into a variable. What I think
OPENSEQ is doing is keeping track of the position where the EOF mark is
so it will know when the end of the file is reached. For a file greater
than 2GB in size, this position is an integer that takes more than 32
bits to store. UV, being a 32-bit application, is not going to be able
to handle it. The maximum positive integer value a 32-bit application
can reference is 2147483647.
The problem is, FV.FILE and FILEVARS(1) are *allegedly* *functionally*
*identical*. An element of a dimensioned array, is supposed to be a
normal variable in every way shape or form.
The problem is that, in this instance, it clearly isn't because the
variable works while the element (allegedly identical) causes a crash.
I'd agree with Perry. It's a bug.
Oh - that reminds me of something else I'd call a bug. It might well
have been fixed by now (I met it in 9.6) but you couldn't safely use a
file variable in an IF statement. Can't remember the details, but it was
something like
FVAR = ""
some conditional code
OPEN FILE TO FVAR
more code
IF FVAR EQ "" THEN
oh the file isn't open, so do whatever
That worked fine on PI, but crashed UV. Perfectly reasonable thing to
do, but UV Basic wouldn't have it. Oh yes - I think it was file
variables declared in common. Common forces all variables to default to
the empty string so all my PI code tested for the empty string. Only to
blow up when we compiled it on UV.
Cheers,
Wol
