Re: how does one specify a record format name when creating a physical file from c?

I fully agree with everything you state.

However, the fact of the matter is that
CRTSRCPF
CRTPF
fopen
all can create files that will have a record format associated with them
(DSPFD). This defaults to the same name as the file.

If I want to rename this entity to something else, I can rename the file and
member names only. I cannot find a way to rename the record format, (or to
name the record format to a different name in the first place).

A record format name is a name that's assigned to a particular format of

within the record that makes up the format.

Therefore, if you want to specify a record format name, you must also
specify all of the field details!

In V5R4, you can specify a record format name from within an SQL Create
Table statement.

In previous releases, the only way to (directly) specify the record
format name is with DDS source.

It can't be done with fopen(), because fopen() doesn't let you specify
the fields and their attributes. But, your C program could create a
temporary source PF in QTEMP, write DDS to that source PF, and then run
the CRTPF command to create a file with the fields and record format
information all specified.

When creating a new file in QSYS using fopen, is there any way of
specifying the record format name?

Alternatively, once the file is created, is there any way of changing
the record format name (of a program described physical file)?

Alternatively, how can I create a physical file from my c program and
specify my own record format name?
