Re: compiling files not replacing old file

Bob/Jim,

The CRTxxx commands do not replace files. However, the CHGPF command
*can* change the layout of the file in place--including any logical files
based on the physical file. Quoting from the help text, "If the format
attributes are changed, the data in the existing file is converted to the
new attributes." The conversion is based on field names so a field name
change means lost data.

There are some other considerations which can impact whether the CHGPF
will be successful or not. The best results occur when the CHGPF is
issued interactively--i,.e., on a green-screen--either from a command-line
or as a PDM option. Submitting the CHGPF to batch (as is basically always
the case from WDSC/RDi) will often fail whereas it will succeed if run
interactively. It's best to read the help text and documentation
carefully. But anyway, we routinely do CHGPF commands and any logical
files which share the record format (i.e., use the same record name and do
not specify any fields) are changed also.

Re: [WDSCI-L] compiling files not replacing old file

Bob

The file compile commands will not replace existing files. That is the
same for both physical and logical files. You have to rename or delete
the existing file, then issue the create command you need. I believe
this is to protect your data in physicals and to protect your programs
from level checks for logical file changes. If you have to take
special steps to create the file, you might remember to recompile the
program(s).

In WDSC 7.0.0.4, I am changing a physical file. I compile it using the
CHGPF option. When I try to recreate the logical files over it, I

find anywhere that will let me tell it to replace the existing file. I
would probably make my files that way if I could, it is all just in my
development library at this point.
