You may not have spaces in variable names like in URL GOTO. This will not work.

You can try out this:
Code:
COUNTER=1
MAX=10
URL_GOTO="www.abc.com/board="
OUTFILE=bla.txt

while (( $COUNTER <= $MAX )); do
        echo ${URL_GOTO}${COUNTER} >> $OUTFILE
        let COUNTER=$COUNTER+1
done

Code:
$ cat test.file

Version=abc
Tab=1
URL GOTO=www.abc.com/board=1
some text...

Code:
for i in seq {1..100}
do  
   awk -v x=$i 'BEGIN{FS=OFS="="} /URL GOTO/ {$3=x}1' test.file >> OUTPUT.file
done
