Hi,
things below is my first thing @ AS:

set fileNum to open for access file "sarigama:as:test" with write permission

set fileEnd to get eof fileNum
write (a as text) & return to fileNum starting at (fileEnd + 1)

It is not necessary to get eof and so long as the file is open, all
new stuff will be written starting at eof, so that's not necessary
either.
If you use a file specification
set f to "sarigama:as:test" as file specification
it is unecessary to bother with filenum and the use of filenum is
_always_ an unecessary complication with no advantages that I know of.
set f to "sarigama:as:test" as file specification
open for access f with write permission
write <something> to f
write <more> to f
close access f

when i didn't place "as text" where it is above
things written in the output file was weird = couldn't read it
things above will spit out
4.294967296E+9

am i doing things in a right way ?
If you want your reals as text then yes, otherwise no. You can write
all sorts of objects to a file.
If your file contains a real number, then you can read it, but you
need to read is as real. The same goes for a list or a record or
whatever.
set f to ("" as Unicode text) & (path to desktop) & "junk.txt" as
file specification
set a to 2 ^ 32
open for access f with write permission
set eof f to 0
write a to f
close access f
read f as real -- <<<<<<<<<<<<<<
i mean ... i should have set a and b in a different way
@ the first two lines
so that i won't have to use "as text" thing?
BTW
can't i have a expressed without "E+9" rapping ?
or i can't get rid of that
simply because a is too huge?
You can get rid of it by parsing the number as text.
