can we send value as well as call smart contract function using CALL

Question

CALL opcode consumes value of the stack (which is transferred to the account). It can also additionally consume stack items to pass input to the smart contract account function.

Can both happen simultaneously? How common is it?

Answer 1

Yes. The CALL opcode has sever parameters: gas, addr, val, argOst, argLen, retOst, retLen

In particular val is the ether amount to be sent, and argOst, argLen are byte array start and length with the input parameters.

See the documentation https://ethereum.org/en/developers/docs/evm/opcodes/ for more details.
