Re: Can you use UDS but NOT lock the data area?



fixed

Scott, it should work to use the UDS so long as you also use the keyword
DTAARA(*LDA).  The line below is copied straight from the manual.
 
 
D LDA_DS UDS DTAARA(*LDA)  
 
Then you can lock and unlock the data area at will.

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
