The answers posted solve your problem for you.
I would just add one tidbit, you can format the numbers
to have leading 0's, so that they line up nicely when
you get a file listing in alphabetical order.
Use format of I3.3 for instance:
string(number,format='("saving",I3.3,".dat")')
Cheers,
bob

Yes, how about,
aux = strtrim(number,2)
or, to solve your whole problem at once,
file = string(number,format='("saving",I0,".dat")')
I use both.

hmmm.
Alternativly if I were to engage my brain before posting, you could just
put a /remove_all in your strcompress call, which would do the business.

Try the /remove_all option in strcompress. Should do the trick.

I have a solution, but it isn't general. If you use:
number = 3
aux = strtrim(string(number),2)
file = 'saving' + aux + '.dat'
It should solve your problem - by removing the space before it appears
in the filename!
The more general solution requires you to call the strcompress a bit
later, and with the /remove_all keyword.
number = 3
aux = string(number)
file = strcompress('saving' + aux + '.dat', /remove_all)
without /remove_all, strcompress compresses all whitespace to a single
whitespace, it doesn't get rid of it.
HTH,
Ben
