Only the first character (capital letter) is effective.
=New
=Old
=Scratch
Note:
New file, there is no practical difference with old file.
Old file
Scratch file, ineffective for the Public Libraries (read only files)
When ’New’ or ‘Old’ is specified, all the members produced are preserved after
the job. If ’Scratch’ is specified, the members are deleted.
The preservation or deletion of the PDS directory is controlled by the
description of shell-script. Even if ‘Scratch’ is specified here, an empty directory
remains when the directory is not deleted by the shell-script. The ’New’
specification requires that the directory of the same name of PATHNAM should be
prepared by shell-script beforehand.
IOMODE(i)
Access mode to file
Only the first character (capital letter) is effective.
=File Direct I/O access to file
=Core I/O access on image PDS file on core memory
Note:
If ‘Core’ is specified, all the information on a PDS file is read into the core
memory at the first access. After this, I/O is carried out from/into the core. A new
member is also written on the actual file.
When the overflow of memory occurs on any PDS file, the Core specifications
to all the PDS files are switched to File mode automatically. The core specification
is effective for the job which takes much I/O time.
The IOMODE specifications to the Public Library files are compulsorily set to
‘File’ mode as they are used only to make User’s Library files and a large amount
of data is stored.
When a series of burn-up calculation is executed, as a lot of members are
written, a sufficient amount of memory has to be reserved. The memory capacity
for PDS files is defined by a parameter statement in an include file.
An example of Block-5 input:
