Stop spaces from appearing when printing to file

[Brad Tilley]

I'm printing some info into a txt file that will be uploaded into a 
MySQL DB. I use ';' as field separaters. How can I stop spaces from 
appearing on both sides of the ';'

When I do this:

print >> x,';',object,";",AN_string,";",ascii,";",sum

My file looks like this:

;12345 ; 23456 ; [1,2,3,4,5] ; 15

I need it to look like this to make the DB happy:

;12345;23456;[1,2,3,4,5];15
