Re: D-spec using the same file name twice

Establishing two separate Open Data Paths [ODP] allows using the same file twice in the a HLL program; available since S/38. The open & I/O would be directed against the same file [member & data], as established by overrides from two separate /labels/ [names] in the program F-specs, redirecting to the one file.mbr:

OVRDBF FILE1 TOFILE(TheLib/TheFile) MBR() SHARE(*NO)
OVRDBF FILE2 TOFILE(TheLib/TheFile) MBR() SHARE(*NO)
Both Declare [for compile] & Open [for run-time] the two separate labels FILE1 & FILE2, both overridden to the one\same file, would effect non-shared opens of the one file named TheFile in TheLib; i.e. establishing two ODPs, as two separate OPENs in the program.

I am not entirely sure of the Declarative statements for row.field data, but for having the separate /files/ from the perspective of the RPG program, I presume it would be no different than handling two files of the same name in different libraries. That can be resolved with similar overrides, as alluded in a recent thread on 10-Nov-2009; in part, by rename the record format of one.?

Can you specify the same file name (physical or logical) more
than once in a program?

I want to process 2 separate records by using the same key, or do
I have to create a new logical with the same key as the file that
already exists?
