DBAToken._tBurnTotal (contracts/DBAToken.sol#33) is never initialized. It is used in:
- DBAToken._tTakeBurnFee(uint256) (contracts/DBAToken.sol#352-359)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

DBAToken._previousBurnFee (contracts/DBAToken.sol#39) is set pre-construction with a non-constant function or state variable:
- _burnFee
DBAToken._rTotal (contracts/DBAToken.sol#31) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _totalSupply))
DBAToken._totalSupply (contracts/DBAToken.sol#30) is set pre-construction with a non-constant function or state variable:
- 100 * 10 ** 6 * 10 ** _decimals
