When you define a data area using UDS, the RPG program will read it
automatically when the program starts, lock it, and update/unlock it
only when the program ends.   That's what UDS is for.

If you want to read a data area without doing that, use the IN & OUT
RPG op-codes instead of UDS.

Here's an example of that:

     D LDA             DS                  DTAARA(*LDA)
     D  RptDate                1      8A
     D  RptType              105    106A

     D MyDtaAra        DS           200    DTAARA('QGPL/MYDTAARA')
     D  LastRun                1      8A
     D  LastRptType          105    106A

      ** Load the LDA.  This does not lock it.
     c                   in        LDA
     c                   dsply                   RptDate
     c                   dsply                   RptType

      ** Load My Data Area.  This does not lock it.
     c                   in        MyDtaAra
     c                   dsply                   LastRun
     c                   dsply                   LastRptType

      ** Load My Data Area again, this time lock it and update it.
     c     *lock         in        MyDtaAra
     c                   eval      LastRun = RptDate
     c                   eval      LastRptType = RptType
     c                   out       MyDtaAra

     c                   eval      *inlr = *on
