Ideal applications can read and/or update sequential datasets, via modeled or unmodeled dataviews.
Is it possible to define a sequential dataview for a variable file (RECFM=V or RECFM=VB)?
No, it’s not possible, as stated on Ideal documentation.
For modeled dataviews:
Variable Length Records
Not supported.
For unmodeled dataviews:
Variable length fields are not supported for sequential files.
