Ethereum: Passing arguments to solidity scripts
When writing intelligent contracts in solidity, one of the most common challenges is to transmit arguments to the scripts. Scripts, specifically
** What are the arguments?
The smart contract. For example, consider a simple contract with two functions: Function Add (A UINT256, B Uint256) {} and Multiply function (A UINT256, B UINT256) {}.
Passing arguments to scripts
Script, you must use the correct syntax to pass variables as function arguments. In solidity, this is usually done using the key word call 'followed by the name of the argument.
For example, in theMycontract:
Solidity
Mycontract contract {
// ... (other functions)
Execution of functions (
Address _feererecipient,
Uint256 _Feebase,
uint256 _taxbase,
...
) Public {
// use the arguments approved here
Call (_Feerecipient, _feebase, _taxbase); // pass the arguments as calls to the function
}
}
In this example, us
Passing complex arguments
If you need
Solidity
Execution of functions (
Address _feererecipient,
uint256 [] _Feebase,
uint256 [] _taxbase,
...
) Public {
// use the arguments approved here
}
Here, we

Example use case
Here is an example contract that demonstrates how to use the 'run' function with different types of arguments:
Solidity
Mycontract contract {
ADD FUNCTION (UINT256 A, UINT256 B) PUBLIC {
// Do something with the sum of A and B
Uint256 = A + B results;
// Pass the argument as a call function
Call (result);
}
Multiply function (Uint256 A, Uint256 b) Public {
// Do something with the product of A and B
UINT256 = A * B results;
// Pass the argument as a call function
Call (result);
}
}
