You can do that by using this general construct:

Code:
string="$string <value to be concatenated to string>"

And you can keep doing this for as many concatenations as you like.

Code:
> cat file1
#!/usr/bin/ksh
string="A string"
string="$string has been lengthened"
echo $string

> ./file1
A string has been lengthened

It doesn't matter whether you use literal strings or variables, you concatenate them in the same way:

Code:
string="$a $b $c ..."
string="one two three four ..."

If you want to store the conents of a file in a variable:

Code:
string=$( cat "$FILENAME" )
