Chapter 17: Scripts

17.1: Escaping from SCRIPT mode
17.2: Entering SCRIPT mode
17.3: Principal Menued Scripts - Feb 1997
17.4: Available Scripts - Feb 1997

The CRYSTALS SCRIPT environment is similar to the menus found in many modern PC programs. Superficially it is rather like a command tree, with a root, branches, twigs and finally leaves which perform discrete crystallographic or data management operations. This sort of structure is adopted so that related operations may be grouped together, making them easy to locate. However, a basic operation may be strongly related to several groups of operations, and must therefore appear on the menu for each of these groups. The same leaf can be found on several different branches! In addition, it is sometimes useful to execute a 'leaf' quite out of its normal context.

This structured flexibility is provided by the SCRIPT processor, and the CRYSTALS program is issued with a sample set of scripts. These have developed to meet some of the needs of Oxford students, and so they may well not be suitable in other environments. However, the scripts themselves are only plain text data files, and users are free to modify them in any way they wish, and add new ones. It is not possible for a script to corrupt the CRYSTALS program.

17.1: Escaping from SCRIPT mode

Control can be passed to the command mode at any time by replying DIRECT (in full) to any SCRIPT question. The users is passed to the CRYSTALS prompt '!'.

17.2: Entering SCRIPT mode

Control can be passed to script mode by issuing the CRYSTALS command. 

          \SCRIPT    scriptname


where scriptname is the name of the script required. The master script is called CONTROL, but entry can be to any branch of the tree directly. Script mode is entered automatically by a call '\SCRIPT CONTROL' in the CRYSTALS startup file 'CRYSTALS.SRT', but can be deactivated by a call '\USE CONTROL' in the users CRYSINIT.DAT file. 

 e.g.
        \SCRIPT  DATA


passes control to the branch concerned with list input, examination and editing. The help facility \HELP SCRIPTS Lists the available scripts on-line.

Numerical data for a structure is stored in a CRYSTALS data-base, filename.DSC. This accumulates information as an analysis progresses. In this file, data is grouped by function into 'LISTS'. Most of the scripts refer to data by its type (e.g. CELL parameters), but occasionally they refer by LIST number (in this case, LIST 1), and many CRYSTALS output messages refer to lists. A table of the lists and the data they contain is appended to this document.
