Re: Managing one physical file with several subfile record formats

Hi Dave

Should I assume that your physical file is internally described? Therefore, you are using fixed format? Free format file descriptions have to be externally described.

Anyhow, with internal descriptions, we have I-specs with record identifiers - this is old school, I've not used this for decades, I think!   :)  And then there would be indicators, IIRC. Nowadays you can give names to some indicators, maybe, for this purpose.

I did look at the SFILE keyword documentation - https://www.ibm.com/docs/en/i/7.3?topic=keywords-sfilerecformatrrnfield#fsfile - you can see whether there is any way to use variables.

Thanks, that's how we always did it!!

I was wondering if I would end up having to do something like
when sfl010,
when sfl020,

for all my read, writes and exfmt or is there anything in the file
definition specifications that would let me have the format name in a
variable.

Hello,

You just need to add SFILE for each subfile :

workstn infsr(*pssr)
sfile(sfl010:sn10##)
sfile(sfl020:sn20##)

Kind regards

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I don't think it's possible to do this but I'm very much outdated and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
