Question multidimensional arrays

I have a file that's logically in the form of a multidimensional array with an unknown number of records in the file. The file looks like this:


How do I load this file into an array for processing, while keeping the two relevant lines of data (i.e., name1, data1) together?

I am working in korn shell, no perl available.

Many thanks in advance!

I do not know the reasons why you want to use two dimensional array,
but here is how you can access both variables:
while read mStr1
  read mStr2
  echo 'Str1 = '${mStr1}' Str2 = '${mStr2}
done < input_file
