Basic Commands - CipherLab 8 Series User Manual

BASIC COMMANDS

This chapter provides detailed descriptions of the commands supported by the CipherLab
BASIC Compiler. In addition to the commands commonly used in traditional versions of
BASIC, a number of commands that deal with specific hardware features of the mobile
computers are supported. These commands are within the user's BASIC programs to
perform a wide variety of tasks, such as communications, LCD, buzzer, scanner, file
manipulation, etc. They are categorized and described in this chapter by their functions
or the resources they work on.
Some commands are postfixed with a dollar sign, $, which means a string is returned
with the command. The compiler will accept these commands with or without the dollar
sign. However, the dollar sign will be postfixed to these commands in this manual and
the sample program.
The description for each BASIC command consists of five parts, Purpose, Syntax,
Remarks, Example and See Also, which are further described below.
