Byte Statement
Declares variables of type Byte. (2 byte whole number).
Syntax
Byte varName [(subscripts)] [, varName [(subscripts)]...]
Parameters
- varName
- Specify the Byte type and the name of the variable to be declared.
- Maximum element number of the array variable
- Optional. Dimensions of an array variable; up to 3 dimensions may be declared. The subscripts syntax is as follows
(ubound1, [ubound2], [ubound3])
ubound1, ubound2, ubound3 each specify the maximum upper bound for the associated dimension. The elements in each dimension of an array are numbered from 0 and the available number of array elements is the upper bound value + 1. When specifying the upper bound value, make sure the number of total elements is within the range shown below:- Local variable: 2,000
- Global Preserve variable: 4,000
- Global variable and module variable: 100,000
Description
Byte is used to declare variables as type Byte. Variables of type Byte can contain whole numbers ranging in value from -128 to +127. Local variables should be declared at the top of a function. Global and module variables must be declared outside functions.

Byte Statement Example
The following example declares a variable of type Byte and then assigns a value to it.
The program monitors whether the top bit of “test_ok” is 1 or 0. The result will be displayed on the screen. (Since the value 15 is assigned to the variable, the bit with higher “test_ok” value is always set in this example.)
Function Test
Byte A(10) 'Single dimension array of byte
Byte B(10, 10) 'Two dimension array of byte
Byte C(5, 5, 5) 'Three dimension array of byte
Byte test_ok
test_ok = 15
Print "Initial Value of test_ok = ", test_ok
test_ok = (test_ok And 8)
If test_ok <> 8 Then
Print "test_ok high bit is ON"
Else
Print "test_ok high bit is OFF"
EndIf
Fend
