Possible values of parameter flag:
0 - carries funds equal to parameter value to destination. Forward fee is subtracted from parameter value. 128 - carries all the remaining balance of the current smart contract. Parameter value is ignored. The contract's balance will be equal to zero. 64 - carries funds equal to parameter value and all the remaining value of the inbound message. Also parameter flag can be modified:
flag + 1 - means that the sender wants to pay transfer fees separately from contract's balance. flag + 2 - means that any errors arising while processing this message during the action phase should be ignored. flag + 32 - means that the current account must be destroyed if its resulting balance is zero. For example, flag: 128 + 32 used to send all balance and destroy the contract.
