Syntax:

BufGetBit(variable reference, position, bit number)

Parameters:

variable reference – The reference to the BLOB variable containing the buffer. For example, 'A'VAR

position – A number defining the position of the byte in the BLOB variable.

bit number – A value from 1 to 8 representing a bit number in the byte.

Returns:

True when the bit is on. False when the bit is off. If the bit number is not valid, the function returns Null.

Examples:

BufSetNum('A'VAR,1,3,2,1) sets the binary value of the first byte to 00000011 by using the default low-hi conversion parameter.

BufGetBit('A'VAR,1,1) returns False

BufGetBit('A'VAR,1,7) returns True

BufGetBit('A'VAR,1,8) returns True
