Thank you for your reply.
As soon as I saved it to a VB
file and searched through the resulting file the different steps became obvious.
Are you able to comment on the use of:
Set oStep = DTSGlobalVariables.Parent.Steps
and the assignment of O and 1 as in
oStep.PrecedenceConstraints("DTSStep_DTSActiveScri ptTask_1").Value = 0
Is this switching certain modules on or off?
