Deleting records in an internal table

Hey everyone, I hope this is a fairly easy question,

I have an internal table, included is two fields from date and to date.

I have been given a date range to delete records based on this range.

For this example I will explain it like this.

FROM TO

1 2

2 3

3 4

4 5

5 6

6 7

7 8

If for example I have been given a range of delete records between 2 and 5.

I want to only delete these records.

2 3

3 4

4 5

but i don't want to delete the record: 5 6

How hard is the to resolve????

Thanks for your help,

Stephen
