How can I use several RDD simultaneously ?
Using multiple RDD in one application is possible; however, certain RDD requires specific treatment. Therefore I strongly suggest you to
read the documentation carefully; we always do this, don't we ?? :)
There are four important issues:
- Specifically ask the linker to include the RDD used, by using REQUEST statement in the main PRG
- Add the RDD Library in the link script using LIB command
- Specify the default RDD, by using rddSetDefault() function
- Use VIA clause when opening a table with different RDD from the default
// Main.prg
function main()
request SIXCDX
request SIXNSX
rddSetDefault( "SIXNSX" )
use Source in 0
use Target in 0 via "SIXCDX"
return nil
