Just use + to concatenate, and string() to cast to string.
name = 'bkg-'+string(i)+'.ps'

Now, one can get blanks, so you can put the whole string into strcompress()
with the /remove_all keyword

name = strcompress('bkg-'+string(i)+'.ps',/rem)

Also, string allows the use of format strings, which is nice if you want alphabetical
listings of the files (the below will add leading zeros for instance.)

name = strcompress('bkg-'+string(i,format='(i6.3)')+'.ps',/rem)

Cheers,
bob
