Hello, I have to convert integers in characters; for example: from
number i=123456 to string c="123456".
I could write in a file the variable "i", and later read it as a
variable "c", but this method seems to me very inefficient.
Some suggestions?

Well, that's almost what you do, however, not to an external file but
to an 'internal' one as defined by your c, as in:

write(c, '(i6)') i

HTH,

First, declare a character variable which is long enough to hold your
bigest integer number:

character(len=15):: iBuf

Second, use the write-statement performing an internal write to the
character variable:

write(unit=iBuf, fmt=*) i

If needed, do something for adjusting the characters:

iBuf = adjustl(iBuf)

If you have some docs for the used compiler by hand, you will find this
feature under internal write statement. Hope, this helps,

Sebastian.

Maybe some thought should be given to giving this process an additional, more intuitive,
name. It's such a common question and "Internal file writing and reading" sure isn't the
first thing a newcomer thinks of when they want to convert int->character or vice versa.

cheers,

And that's really, really how you want to think of it. Because if you
think of it that way, most other things about its usage pretty much
follow (ok, not all of them, but most of the basics). For a very
particular example, it is "obvious" when you want to do an internal read
versus an internal write. If that isn't obvious, then I'd say you aren't
yet really thinking about the character variable as a substitute for a
file. If you don't think of it that way, then you'll be like all the
other people who just try to memorize when to use read versus write, and
who guess wrong pretty much 50%% of the time.
