Yes, there is. But in fact there is a better (and MUCH better readable) way to accomplish this if you use arrays - a feature almost every modern shell offers:

Code:
#! /bin/ksh

table[1]="table1" ; col[1]="col1"
table[2]="table2" ; col[2]="col2"
table[3]="table3" ; col[3]="col3"
table[4]="table4" ; col[4]="col4"

counter=1

while [ $counter -le ${#table[@]} ] ; do
     echo "TABLE: ${table[$counter]}     COL: ${col[$counter]}"
     (( counter += 1 ))
done

${#arrayname[@]} is an automatically maintained integer giving the number of elements in the array arrayname.

I hope this helps.
