Abstract

A method for accessing a common set of culturally sensitive display width services has been disclosed. The access methodology is independent of the programming language chosen (COBOL, FORTRAN, PL/I, RPG and C) and is provided as a set of language independent procedure calls.

Language Independent Interfaces for Culturally Sensitive Display
Width Services

      A method for accessing a common set of culturally sensitive
display width services has been disclosed.  The access methodology is
independent of the programming language chosen (COBOL, FORTRAN, PL/I,
RPG and C) and is provided as a set of language independent procedure
calls.

      The defined set of common NLS display width services provides a
consistent interface to the user without requiring the programmer to
code with a specific culture in mind, and broadens the choices of
operating systems and programming languages for which and in which
the product may be developed.

      These services are keyed off the user's local profile
information which identifies preferences for various presentation
formats of the culturally sensitive information.  The POSIX concept
of 'locale' has been adopted as the means of specifying the
installation's or user's preferences.

      The subject of this disclosure is the adaptation of a
programming language independent interface to these culturally
sensitive display width routines.  This will enable the use of these
routines from a wider range of programming languages consistently
across a wider range of computing platforms.

      The use of C function prototypes allows the specification of
the argument list as well as the data type of each argument to be
done accurately and concisely in one place.  It also clarifies
whether a parameter is passed by value or reference.

      The services are described as standard procedures, rather than
as functions, because not all programming languages support the use
of function calls.

The main features of the functions, outlined below, include:
  o  the use of the localized information in processing data to
      provide culturally correct results
  o  the acceptance of a localization indicator, in the form of a
      specific named resource, on each invocation
  o  the provision of error handling which gives specific information
      such as the offset into the string whe...
