*IT is much better at working with programs with line numbers.  ED+ just treats the line numbers as part of the code, with no functionality to renumber or maintain auto numbering as you insert lines.  What I wish *IT had was code formatting with indention of loops and {} if blocks (and code folding would be nice too).  It's easy to get lost in long, deeply nested sections.  I work with both, depending on if I'm willing to remove line numbers, which for much existing code I can't.

There is one built into ED+.

Simply load the program into ED+ then select Tools >> Reformat from the menu bar. 

You can then save the resultant as a sequential file.

The issue may be related to invalid data in your file.  PxPlus doesn't, by default, validate that the data you write into the files matches the data dictionary specifications. On the other hand, ODBC access relies on the fact that the data adheres to the specifications.

What might be happening is that there is a field whose contents is larger than expected thereby causing a memory access problem.

To check this try running the Verify Data option on the Database export utility.  Basically pretend you are going to export your data to a database, launch the export utility from the data dictionary and select "Verify Data".  It should read through your file and check that the file contents adheres to the Data Dictionary specifications.

Good luck

The crash is happening in a Microsoft Windows DLL: ntdll.dll.

Is this only happening on this one Windows system?

Is it reproducible on other systems?

This is actually a Linux issue.  Record locking is done by placing a Write lock against the file however Linux doesn't allow us to add a write lock to a read only file.

Also, since the EXTRACT directive can be used to position the file PxPlus could not return the error. A fairly common coding technique looking to read records starting with a known record key is to use an EXTRACT to the desired starting record then create a loop doing a standard READ next.  The EXTRACT positions the file such that a subsequent read next will return the extracted record making the coding cleaner.
