Variables

The are two variable types, integer variables and string variables. Variable names must start

with a letter and may be followed by letters ( A-Z, a-z ), digits ( 0-9 ) or an underscore ( _ ).

No other characters are permitted in variable names. All variables are global and may be

accessed from any subroutines or threads.

Integer variables

There are three types of integer variables used to store numbers.

var X1

int32 X2

int16 X3

int8 X4

Variable types var and int32 are identical, they are just two names for the same thing. These

integer variable types are stored as 32 bit signed numbers. The range of values that can be

stored is from -2147483648 to 2147483647.

Variables of type int16 hold 16 bit signed numbers. The range of values that can be stored is

from -32768 to 32767.

Variables of type int8 hold 8 bit signed numbers. The range of values that can be stored is

from -128 to 127.

It is recommended that 8 and 16 bit variables are used only when you absolutely must. This is

likely to be when locating variables in eeprom memory which is limited. For general use there

is no point in trying to save memory if your application is only going to be using part of it.

Internally dScript uses 32 bit numbers for all calculations anyway, so always try to use var

types, or int32 if you prefer.

You can have any number of integer variables up to the limit of the on-board RAM memory.

Variables can be named as you choose. Short names like x and y are fine, but there are no

built in limits to the length of the name, so be descriptive in your choices. Variable names are

case sensitive so:

var mycounter

var myCounter

are two different variables.

Variable names are not loaded into the module. All variables are compiled to an index code, so

long variable names neither consume valuable memory space on the module or slow down

program execution.
