My script is really huge so, right after the sed line, I added
echo "before+increment=$[$before+$increment]" >> REPORTFILE
echo "Wrote : `grep WORD FILE`" >> REPORTFILE
When I look in the REPORTFILE file, I can read :
before+increment=12
Wrote : WORD 12
So
WORD 10 10 10
really became
WORD 12
This is the same with single quote like in my fisrt post, or with double quoted sed :
sed -i_temp "/WORD/s/$before/$[$before + $increment]/g" FILE
Thanks a lot for your help,

TOUCH(1) User Commands TOUCH(1)
NAME
touch - change file timestamps
SYNOPSIS
touch [OPTION]... FILE...
DESCRIPTION
Update the access and modification times of each FILE to the current time.
A FILE argument that does not exist is created empty, unless -c or -h is supplied.
A FILE argument string of - is handled specially and causes touch to change the times of the file associated with standard output.
Mandatory arguments to long options are mandatory for short options too.
-a change only the access time
-c, --no-create
do not create any files
-d, --date=STRING
parse STRING and use it instead of current time
-f (ignored)
-h, --no-dereference
affect each symbolic link instead of any referenced file (useful only on systems that can change the timestamps of a symlink)
-m change only the modification time
-r, --reference=FILE
use this file's times instead of current time
-t STAMP
use [[CC]YY]MMDDhhmm[.ss] instead of current time
--time=WORD
change the specified time: WORD is access, atime, or use: equivalent to -a WORD is modify or mtime: equivalent to -m
--help display this help and exit
--version
output version information and exit
Note that the -d and -t options accept different time-date formats.
GNU coreutils online help: <http://www.gnu.org/software/coreutils/> Report touch translation bugs to <http://translationproject.org/team/>
DATE STRING
The --date=STRING is a mostly free format human readable date string such as "Sun, 29 Feb 2004 16:21:42 -0800" or "2004-02-29 16:21:42" or
even "next Thursday". A date string may contain items indicating calendar date, time of day, time zone, day of week, relative time, rela-
tive date, and numbers. An empty string indicates the beginning of the day. The date string format is more complex than is easily docu-
mented here but is fully described in the info documentation.
