Multiple file and single parameter file

Hi Team,

In our project we have written below 2 scripts like

Script1:
Shell script start & END
Begin Audit process - uses teradata bteq
END Audit Process

Script 2: Environemtal variable file different

Now Client ask to change this requirement and need below files:
Script1:
Shell script start & END

Script2:
Begin Audit process - uses teradata bteq

Script3:
End Audit process - uses teradata bteq

Script4:
Environemtal variable file

My question is how to call these 1,2,3 file stepwiase. Also how should i make sure that this single paramter file is getting used by alll 3 files??? Please guide.....

Trying hard to interpret this vague and unclear request, I'd say you create a fifth script that sources all above scripts in sequence, e.g.

. Script4
. Script1
. Script2
. Script3

IF the assumption that Script4 is the "single paramter file" holding variables for all three other scripts is correct.
