How to understand the routines in datastage

[abha.kalra]

give some information how to write datastage routine and how to understand the already written code.

here is the some sample code.

$INCLUDE DSINCLUDE JOBCONTROL.H

Equate RoutineName To 'CoEGetLinkCounts'
Equate RunIntfName to Arg_IntfName
Equate RunJobName to Arg_JobName
Equate AuditPath To @PATH:'/seqfiles/auditfiles/'
Equate JobRunId To '100'
Equate CurrLinkName To ''
Equate PrevLinkName To ''

Deffun DSRMessage(A1, A2, A3) Calling "*DataStage*DSR_MESSAGE"
Deffun DSRTimestamp Calling "DSR_TIMESTAMP"

JobHandle = ''
Info = ''
AuditRow = ''
AuditRow1 = ''
ReturnArray = Arg_PrevArray

JobHandle = DSAttachJob(RunJobName, DSJ.ERRFATAL)

Hi

I think the routine you have given is not complete.
Pls give the complete routine to infer something from it.

Abha,

as Manoj has already pointed out, the code portion you added to your post is just the initial header portion of a job. It sets the values to some constant and variables and attaches, or opens, a job for use.

The programming language is called BASIC and the complete manual is on your DataStage client PC as a .pdf file. If you look at some of the builtin and SDK routines in the Manager client you will see how the language works. If you come from a well-founded programming background in any structured programming language it is just a matter of learning the syntax and finding out what functions are available to you in DataStage BASIC.
