Overview of Internet Basic
Welcome to Internet Basic, the fastest and easiest way to create professional Internet and intranet applications. Internet Basic offers a variety of interfaces, including:
The type of interface you choose depends on the type of application you are writing and the requirements of the user. Internet Basic provides the programming tools to meet all of the above needs.
- Character-based applications, for both local and remote users
- Graphical applications (with Windows controls and dialogs), for both local and remote users
- Web-based applications, for intranet and Internet users (XAP)
- Internet protocol applications, such as e-mail (SMTP), file transfer (FTP), and hypertext (HTTP)
- Database applications (including ODBC)
- Data mining applications
- Hardware-specific applications (serial devices, fax/modems)
Internet Basic offers many powerful programming features, including:
- an array of easy-to-use input/output statements
- record locking and file locking capabilities
- numeric values up to 16 digits, with up to 15 decimal place
- advanced subroutine and subprogram features
- encryption and decryption functions
- uncomplicated commands for trapping and handling runtime
- a full complement of string and numeric functions
- conditional compliation of source code sections
- direct access to low-level operating system functions
Internet Basic was designed with efficiency in mind.
A good portion of the object code created by the Internet Basic compiler results in calls to a powerful runtime system called Comet.
This means extremely small, more efficient object code. This also means that Comet's advanced file management system and communications capabilities are available to all Internet Basic programs.
Internet Basic source programs are divided into three sections:
- Data Division
Statements in this division define the data variables to be
used in the program, including specifications for data type,
size, and other attributes. One exceptional feature is Internet Basic's
ability to declare data as "common" to be used in multiple
program overlays and/or subprograms.
- I/O Format Division
The division includes statements and control codes
for input/output formatting and interfacing with
external devices/data sources.
- Procedure Division
The Procedure Division includes executable statements that
control program flow, input/output, processing, and exception
