6. Utility for PDS File Management
Printed information on the 99th device may be insufficient for the user’s demand or may be not
convenient for tabulation and plotting. In the PDS files such as FLUX, MACRO, MACROWRK, and
MICREF, a lot of information is stored as binary data. Here, several utilities to extracting necessary
information from PDS files are shown.
6.1 PDSTOTXT and TXTTOPDS
(1) PDSTOTXT [ ~SRAC/util/pdscnvt/shr/pdstotxt.sh ]
The PDSTOTXT is a program to convert the content of a member in PDS file into a text file. It
is used to dump the contents of members in PDS file or to transfer the members into a machine of
different data organization.
(2) TXTTOPDS [ ~SRAC/util/pdscnvt/shr/txttopds.sh ]
The TXTTOPDS is a utility program to reconvert a text file converted by PDSTOTXT into PDS
file.
By using PDSTOTXT and TXTTOPDS, it is available to transfer PDS files between machines
with different data organization. By these utilities, Public libraries and MACRO files of SRAC can be
easily transferred from a machine to others.
6.2 PDSMDL
The PDSMDL (PDS modular subroutine package) is not a complete program but a group of
modular subroutines for the user to edit the contents of a member of PDS file. The user makes a main
program where the suitable subroutine(s) is (are) called by CALL statement so that the user can read in
an array from a member into his defined array, or update the contents of a member. The user who is
acquainted with FORTRAN and PDS file in SRAC can utilize these modules in a wide range of
applications such as calculation of the reaction rate of arbitrary reaction and transfer of cross-sections
into another code, etc. The current library includes 13 modules. The usage including the meaning of
arguments are described in the source program of each module [~SRAC/util/pdsmdl/modl/*.f].
