Spool is the printer area queue where all the items are queued up to be scheduled for printing.

Instance is a like a copy of / like an particular object.

hi Surekha,

1.A roll area is memory that is allocated by a work process for an instance of a program.

It holds information needed by R/3 about the program's execution, such as:

The values of the variables ..The dynamic memory allocations and

The current program pointer

2.Spool is a work process which passes sequential datasets to a printer or to optical archiving.

Within ABAP, sending a list to the SAP spool system is generally called 'printing lists'.

3.Q.what is an instance ?
