xmlplo

This program is used to demonstrate the input and graphical display of SAS data from different sites. The program includes changing tag-dictionaries which match tag names to typical parameter key numbers in current use at the ILL. This file (default in2ill.now) also contains multipliers which , for example, allow typical scattering vectors to be given as Q_A-1 or Q_nm-1.

in2ill.now
The file starts as follows,after a title line..

keynumber...multipier.../xml_tag_name  for conversion to ILL keyed fields
100  1.  /"Q_A-1"
100  10. /"Q_nm-1"
200  1.  /"S_counts"
200  1.  /"I_counts"
200  1.  /"I_cm-1"
300  1.  /"Sdev_counts"
300  1.  /"Idev_counts"
300  1.  /"Idev_cm-1"
400  1.  /"Qdev_A-1"
400  10. /"Qdev_nm-1"
500   /"Title"
600   /"Title"

2    1.  /"x0_cm"
2    0.1 /"x0_mm"
3    1.  /"y0_cm"

Graphical environment

A simple batch file sasplo.bat has been written to set up the environment variables used within the ILL PGPLOT graphics library. The environment variable PGPLOT_DIR must be set to the directory containing GRWND.exe, the font file, grfont6.dat etc.

Running the program

 
D:\2007\xmlplo>sasplo
D:\2007\xmlplo>REM BATCH file for xmlplo run from this directory
D:\2007\xmlplo>REM Graphics require grfont6.dat, GRWND.EXE in directory PGPLOT_DIR
D:\2007\xmlplo>set PGPLOT_DIR=.\
D:\2007\xmlplo>set PGPLOT_ILL_DEV_1=/GW
D:\2007\xmlplo>set PGPLOT_ILL_DEV_2=/VCPS
D:\2007\xmlplo>xmlplo
