Hi!
I must work with big amounts of data, and I'm having some problems with
read-dowhatever routine:
file_ref is file opened for access
"starting_at" uses to be 1
The problem is with fEoF (eof of file opened for access). If we are talking
about a 800MB file, it will throw an error "can't make fEoF into an
integer".
I've been giving an eye to the Standard Addns' dictionary, whence the
present late contribution to JJ's thread.
I see that "read" is supposed to accept "double integers" as the
"from" and the "for" parameters.
But I cannot have it work:
-----------------------
read f for (20000000000 as double integer)
read f for ("20000000000" as double integer)
read f for (double integer (20000000000))
...
-----------------------
nothing I could think of works.
Not surprisingly, AppleScript is not able to store a "double integer" variable:
-----------------------
set x to 20000000000 as double integer
class of x --> real
-----------------------
but, more surprisingly, the Apple Event Manager itself seems to be
unwilling to accept the double integer (aka "comp") as a parameter.
So finally I would humbly propose that "read" is bogus - or the
dictionary lies, it's up to Apple.
