Managing one physical file with several subfile record formats

Hello,

I don't think it's possible to do this but I'm very much outdated and maybe
there's something that can help :

FMYFILE CF E WORKSTN
F SFILE(MySFRecord:SFRRN)

MYFILE is the name of the display file, but MySFRecord would be variable.

I have a simple program that reads records from a flat physical file into a
subfile, manages these and updates the physical file from them.

Now I need to add different subfile record formats and do the same, still
managing the same physical file.


Thanks
