UByte Statement

Declares variables of UByte type. (unsigned variable type, size: 2 bytes).

Syntax
UByte varName [(subscripts)] [, varName [(subscripts)]...]

Parameters

varName

Specify the UByte 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 Optional.
(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
UByte is used to declare variables as UByte type. Variables of UByte type can contain values from 0 to 255. Local variables should be declared at the top of a function. Global and module variables must be declared outside functions.

UByte Statement Example
The following example shows a simple program that displays some values as Bit7 using UByte.

Function main
    UByte varByte

    varByte = 127
    Call BitCheckUByte(varByte)

    varByte = 255
    Call BitCheckUByte(varByte)
Fend

Function BitCheckUByte(var As UByte)
    Print "Value:", var, " Bit7 =", BTst(var, 7)
Fend

[Output]

Value:127 Bit7 = 0
Value:255 Bit7 = 1
