oracle output file

i have this script for oracle spooling the file to an output file.
the script is like the following:

set linesize 115
set space 0
set colsep ';'
set pagesize 0
set echo off
set feedback off
spool /home/bscs6/scripts/billrun.log
select trim(both from glecode),trim(gladesc),ltrim(abs(sum(gleamt)))
from glentry_all,glaccount_all
where gleentdate in (trunc(sysdate - 6))
and glecode=glacode
and  substr(GLEREM,11,2) in ('01','02','04')
group by glecode,gladesc;
spool off

and the output is like this:

100300                        ;A/R Customers                                               ;      100.00
200900                        ;Tax from Receipt                                            ;      100.00
300400                        ;Revenues from Usage Charges                                 ;      100.00

and i want the output to be like this:

100300;A/R Customers; 100.00
200900;Tax from Receipt;  100.00
300400;Revenues from Usage Charges; 100.00

how can i fix this?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

although there might be a way to achieve this using sqlplus options (which I'm not aware of), I'd suggest  trimming the output file after it has been created, e.g. this way -
awk  -F";" '{gsub("  ","",$0); printf "%s;%s; %s\n",  $1, $2, $3}'   /home/bscs6/scripts/billrun.log >  /home/bscs6/scripts/billrun.log.trimmed
Please note that there are two spaces between the quotes just following "gsub(..."
