Planning to place compiler phases in shared storage
The following sections define shared storage, describe the various compiler phases, and explain why you might want to place the compiler phases in shared storage.
You might want to make some program objects resident in a link-pack area in order to minimize the search for them when an Enterprise COBOL program is run or when the objects will be shared. You might also want to make some or all of the compiler phases resident.
The term shared storage is used generally to describe the link-pack area (LPA), the extended link-pack area (ELPA), or modified link-pack area (MLPA). Except where specifically otherwise stated, all three terms are implied when the term link-pack area is used in this information.
