gas: amount of gas to send to the sub context to execute. The gas that is not used by the sub context is returned to this one.
address: the account which context to execute.
value: value in wei to send to the account.
argsOffset: byte offset in the memory in bytes, the calldata of the sub context.
argsSize: byte size to copy (size of the calldata).
retOffset: byte offset in the memory in bytes, where to store the return data of the sub context.
retSize: byte size to copy (size of the return data).

* FE no es necesario (investigar?)
* En el contrato 1 usar push1 en vez de push32 para ahorrar gas en el deploy
* En el contrato 3 en vez de 0256 usar 0064, y también usar entonces push1 en vez de push2
