The original listing user of an order can at any time select the placed order from the open orders list and press the Close Order button to cancel the order. In other words, the opcode budget is pooled across the group, including inner contract calls. With TEAL version 6, Algorand smart contracts can make app to app calls using inner transactions. The contract is then compiled and funded using the goal command-line tool and the Algorand dispenser. When calling a contract from a contract, an additional 700 opcode budget is allocated to the entire transaction group. EIP-11252019AF was introduced and passed to delay vesting compared to the original schedule, giving Algorand more room to grow. . However, TEAL is essentially an assembly language.
