pascal error handling
In Pascal, error handling is achieved through the use of exception handling mechanisms. These mechanisms allow you to catch and handle different types of exceptions that may occur during the execution of your program.
To handle errors in Pascal, you can use the try..except
block. The try
block contains the code that may raise an exception, while the except
block is used to handle the exception if it occurs.
Here's an example of how to use exception handling in Pascal:
try
// Code that may raise an exception
// ...
except
// Code to handle the exception
// ...
end;
Inside the except
block, you can write code to handle the specific exception that occurred. This can include displaying an error message, logging the error, or taking any other necessary action. You can also have multiple except
blocks to handle different types of exceptions.
Additionally, you can use the finally
block to specify code that should always be executed, regardless of whether an exception occurred or not. The finally
block is optional.
try
// Code that may raise an exception
// ...
except
// Code to handle the exception
// ...
finally
// Code that will always be executed
// ...
end;
By using the try..except
block, you can effectively handle errors and exceptions in your Pascal programs.
