IV Abstract
VPL stands for "Vector Processing Language". The main feature offered by this program is a flexible
easy to use command language for data analysis and presentation. This tool as well as general functions
to manipulate vectors (Fortran-like expressions, IF and DO loop structures, procedures) offers a data
base interface and a graphics package. It offers also specific tools for thermal-hydraulic analysis such as,
thermodynamic fluid property functions, heat transfer coefficient calculations and drawings of schematic
nuclear reactor components. Introduction
VPL is based on the experience gained in the framework of the LOBI1 Project on the analysis of experimental
results and code predictions using the STARSIS package [1] and its improvements [2], [3], [4]. However, the
need for a new general purpose tool that can be used not only for analysis of data stored in a data base
[5] but also for complex manipulation of data base vectors led to the requirements of the VPL program,
with a new command language for data processing, keeping the improved STARSIS graphics package and
interfacing by a new software with the STARSIS data base.
VPL2 allows you to enter, manipulate and plot vectors of data by an easy-to-use mnemonic command syntax.
Vectors can be entered by DATA command, expressions, tablet, sequential files or by,data-base; they can
be processed by expressions using the same notation as PORTRAN-77 language; they can be printed on a
screen or plotted producing black & white or colour graphics in 2 or 3 dimensions; finally it is possible to
store the vectors on a data-base or in sequential formatted files.
VPL can work in batch and/or in interactive manner by procedures, DO loop structures, IF command,
symbolic substitution and so on. Suppose you want to plot a graph based on the same variables stored in a
data-base, however from different sources (different experiments, different predictions, etc.). You can define
a procedure where VPL asks you only the name of the experiment (or prediction) and then executes the
procedure as required, each time repeating automatically the whole set of VPL commands.
In VPL are available a large set of mathematical functions as in FORTRAN and in addition functions
for interpolation, differentiation, integration, polynomial regression, vector manipulation ands to
calculate fluid property by interpolation of tables stored in a data-base.
In VPL is also available a package to build fluid property tables and a package to calculate heat exchange
between solid structures and two phase fluids. It is used for experimental data and calculation results analysis,
to check correlations for code improvement and to provide an environment for the RELAP5/EUR-MF code.
VPL is written in FORTRAN-77 standard and uses the IGL graphics library. At this moment it is available on
JRS's Amdahl mainframe. It can work under TSO system on Tektronix graphics terminal, any alphanumeric
terminal and also under BATCH system. It is ready for implementation on other computers or for interfacing
with any other graphics library when necessary.
