When using the Mainframe Express Data Tools Find and Replace, COMP-3 items are not being found.

In the record the value of comp-3 items have been translated into string and are not the actual byte value. When doing a text find the bytes in the records have to match the byte value of the text string you have entered and so comp-3 items cannot be found when using the text search. To find comp-3 items enable the hex field in the Find/Replace dialog and enter the value you wish to find.
