Series 3000 Application Programmer’s Guide
You have now seen an example of each of the two basic methods for
programming Series 3000 terminals. The rest of the programming task builds
on what you already know about writing application programs and on special
features of the Series 3000 terminals. The remaining chapters of this manual
describes these features and discusses how to include them in your
applications. The following section summarizes these features and provides
brief descriptions of the application programming interfaces (APIs) available
for accessing them.
Application Programming Interfaces
The Series 3000 has a rich set of Application Programming Interfaces (APIs).
These APIs can be grouped under the following headings:
File Function APIs
Three sets of file function APIs are provided to supplement the Microsoft C
libraries:
Microsoft C Run-Time Library. These are the standard Microsoft
libraries, with some of the code modified for use in Series 3000 terminals.
DR DOS Library. This library supplements the Microsoft library
routines, providing functions necessary for accessing special functions of
the Series 3000 terminals.
URM and File Manager Libraries. The UBASIC Record Manager (URM)
and File Manger provide UBASIC-compatible file organization. Some
Series 3000 features are most easily accessed using these APIs.
For more detailed information on these file management APIs, refer to:
