Replying to this message, because I am too lazy to find the Opening
Post or my reply suggesting similar and also because the quoted text is
a good lead-in.
And there is also the option to use OPNQRYF to share the ODP with an
RLA program [although I am under the impression this is not what the
Original Poster wants], with the selection performed by the query, most
likely using the QRYSLT parameter. Although not a /logical file/
specifically, it is in effect a logical view\path to the data, and a
temporary query ODP may be more desirable than a temporary logical file.
A possible example:
dcl &svDateTime *char 20
dcl &todaysdate *char 08 stg(*defined) defvar(&svDateTime 1)
rtvsysval QDATETIME &svDateTime
ovrdbf thefile share(*yes) ovrscope(as_appropriate)
opnqryf thefile qryslt('OHORDT *eq' *bcat &todaysdate) opnid(tf)
/* do here what is required of\with the shared ODP; e.g. CALL */
clof opnid(tf)
