2.2.3. Constants and Variables
All constant, variable and system element names must start with an
alphabetical character (a-z, A-Z) and may be followed with up to 31
alphabetical characters, numbers (0-9) and underscores (“_”). Keywords
may not be used as names. For detailed information on any of the constants
and variables (including examples), refer to the SERVOSTAR
MC
Reference Manual.
2.2.3.1. CONSTANTS
Constants are numbers, which are written as ordinary text characters; for
example, 161. Constants can be written in decimal or in hexadecimal (HEX).
To write a constant in hex, precede it by a 0x; for example, 0xF is the hex
representation of 15 decimal.
The MC provides numerous literal constants (reserved words with a fixed
value). You can use these constants anywhere in your program to make your
code more intuitive and easier to read. For example:
A1.Motion = ON
turns on the A1 property Motion. This is more intuitive to read than:
A1.Motion = 1
although the effect is identical.

2.2.3.2. VARIABLES
You must declare a variable in MC-BASIC before you can it. In the
declaration, you define variable name, scope and variable type. MC-BASIC
supports Long for integer values, Double for floating point values, and String
for ASCII character strings.
