Language Command

The menus shown in Figure 2 provide all of the functions that are required to collect, reduce, and archive the data. The menus, which are actually programs written for the operating system s command language interpreter, conduct dialogues with the user that translate... 

The core of the current version of Candid is implemented in standard Fortran-77 and has been built upon the data structures and into the framework of the user interface of the program Dyana. The standard schedule and parameters for a complete automated structure determination with Candid and Dyana are specified in a script written in the interpreted command language Inclan that gives the user high flexibility in the way automated structure determination is performed without the need to modify the compiled core part of Candid [26].

Mistake 1 Novice writers, accustomed to lab manual Instructions, sometimes describe procedures using command language rather than passive voice. 

Another useful feature is the command script. This built-in command language enables users to automatically perform calculations at a series of P, V, or T values that is, to submit a batch of calculations and save every set of results. Thus users can parameterize and initiate a set of calculations and walk away when they return, the data is ready to be analyzed - the real challenge ... 

In fuzzy logic, the use of fuzzy if-then rules is governed by the calculus of fuzzy rules, CFR. A major part of CFR is the Fuzzy Dependency and Command Language, or FDCL for short. Basically, FDCL is a fuzzy programming language that provides a powerful tool for the representation and manipulation of imprecise or ill-defined dependencies. Two issues play pivotal roles in FDCL. The first is interpolation, and the second relates to the induction of rules from observations. 

Macros. A simple command language can be used to create a series of predetermined steps that the program will execute whenever ALT and an appropriate label key are pressed. Such a grouping of commands is called a macro. A macro can be used to extract data from a data base, to perform a series of mathematical operations (such as finding the roots of a nonlinear equation), or to prompt you for desired data changes. 

Because of the rich command language of both X-PLOR and CNS, the calculation could be implemented in both X-PLOR and CNS scripts of about 1,000 lines each. The scripts are available from our web site biology.polytechnique.fr/biocomputing. 

Another major characteristic of front end systems briefly mentioned in the context of query uploading is the ability to perform query translation. In general, each host computer uses its own own command language and, particularly in the field of bibliographic and other textual data bases, a query translator is desirable to ensure that a particular query can be searched against the many and varied relevant files on diverse host computers. In chemical structure systems, the only query translator available to date is TopFrag...
