External call options

Why use this example

Use this pattern to test contract composition, external calls, events, and return values inside one reproducible run. The entry isolates external call options so its input, result, and state changes stay easy to compare.

Solidity to run

contract PayableTarget {
  function deposit(uint256 bonus) external payable returns (uint256) {
    return msg.value + bonus;
  }
}

PayableTarget target = new PayableTarget()
target.deposit{ value: 1 ether, gas: 100000 }(2)

Official Solidity reference

Compare this focused investigation with the complete language definition in the Solidity documentation.

What to expect

The typed call forwards 1 ether with an explicit gas allowance and returns that value plus two wei.

Continue the investigation

Change a value, add another expression, or open Inspect after the run. Accepted entries remain available to the next entry, and the clean replay keeps the complete result reproducible.
