DataStage macros are defined in JOBCONTROL.H, which is to be found in the DSINCLUDE directory.
If you inspect how they are defined, it will become clear that there is no capacity in the mechanism for passing dynamic arguments to them. Instead, you need to call the embedded function directly.
Example of DataStage macro definition:
Code: Select all
$IFNDEF DSJobName
$DEFINE DSJobName DSGetJobInfo(DSJ.ME,DSJ.JOBNAME)
$ENDIFThe $DEFINE declaration is a compile-time substitution. It does not have an argument-passing mechanism.
