%ADDR and possible pointer problems

Since we installed Version of the RPG compiler with the attribute o/s current we have been encountering problems with a technique that previously worked ok.

With the third parameter we pass the address to a data structure :-



wrkCRtn = cpReadI( XmoYAccVal : XmoCValeur

: %addr(vlxopc) )







In the called function we do the following



PcpRead B Export



d Pi Like( Tint )

d ii_YAcc 1 Value

d ii_CVal 12 Value

d PtrVlXOpc Like( TPointer ) Value

d Options( *NoPass )









d vlxopc e ds extname(dvlxopc)

d Based(PtrVlxOpc)





Has anybody had problems with this technique ?



Yesterday I got a messages that an objet had been partially or entirely destroyed and could not be used followed by a recursion exception !!



I recompile the program and it now works ! I suppose the allocation of memory may be a bit different and as such the (I suspect) pointer error no longer occurs.



I am thinking of identifying and where possible replacing this technique ( %addr ) by passing the ds itself.





I did read a comment my Hans Boldt that this technique should be avoided. I should perhaps leave the use of this technique for use with API access only.



What do you all think
