Is this the correct syntax/values to create an EDIT file during runtime?
It's still being created as Entery Sequence.

The main mistake is that the "2" you are passing as the fifth argument is the file type number for Entry-sequenced. That value should be a 0 to specify an Unstructured file type. Unless you want to specify a non-default value for the maximum number of extents, you could stop the parameter list with that fifth argument. All arguments past the last one you include are treated as OMITTED. (The block length is not used for unstructured files.)

The documentation says you should use the procedure FILE_CREATE_ instead of CREATE in new code, so it would be a tiny bit better for you to change to call FILE_CREATE_ instead, but it really doesn't matter.

You have 2 in the file-type parameter, that is EntrySequenced
file-type 0 is unstructured

Rather than trying to use URLs that point into HPE's library, I always go in from the top:
www.hpe.com/info/nonstop-docs

From that page, click on the link for L-series or J-series, as appropriate, then enter keywords to search for the manual you are interested in. In the search results, click on the manual title to open the manual and you can read it in your web browser.

For manuals I reference often, instead of bookmarking the manual's URL, I download the PDF to my computer -- when you open a manual, there is a button near the top of the window for downloading the manual.

Hi, Adam,

Keith and JShepherd's comments will create an Edit file correctly, albeit an empty one.

If you then intend to open and write to it though, you can't just use FILE_OPEN_ and WRITEX calls. The resulting file will be declared corrupt by programs that try to riead it.

You can find information in the IOEdit procedures which are used to write edit files in the Guardian Programmer's Guide,
in the chapter labeled "Using the IOEdit Procedures'. Alternatively, since your code appears to be COBOL,
you can use the standard COBOL verbs to Open (for Extend is preferred), WRITE and CLOSE.

But it's probably usefult to use variable length records in those writes.

Good luck!
Bill
