Answer / sameer

Every job has an *LDA created by the system. To see the
*LDA of your current session you logged in - DSPDTAARA *LDA.
You can pass the same to other's job LDA by psssing it as
parameter of the program of the job we are calling. This
way informaton floats between different jobs.

Answer / prabhas

Data area is a storage area to store limited information.
Example: a new and unique customer number is generated
whenever a new customer is added to customer master file.
Data area keeps track of last record added and add 1 to it.
Through program we can access new customer number.

To create a data area, use the command CRTDTAARA (Create
Data Area). For example, to create a 100 character data
area named LASTINV#:


Now, load the first 10 positions with the
value "AA12345678" with the CHGDTAARA (Change Data Area)


Look at the value of the data area with DSPDTAARA (Display
Data Area):


A CL program can retrieve the value with RTVDTAARA. An RPG
program uses the "IN" operation to retrieve the value and
the "OUT" operation to change it.
