Exceptions in KAGSA

Exceptions is an important in all programming language
Here we have to keywords : try, catch

Example

this is wrong kagsa code because you can't covert abc to an integer :

write toInt('abc')

if i run it i will get

error catched [ test.kg/ValueERR ]
   |
 1 | write toInt('abc')
   |
error : can't change (abc) to int

the error file is : file.kg
the error line no : 1
the error line : write toInt('abc')
the error type : ValueERR
the error text : can't change (abc) to int

How We Can Run it Without get an Error ? we can use try and catch

try {
    write toInt('abc')
}
catch {
    write 'There is a Error in Your Code'
}

Output :

There is a Error in Your Code

Ok its Clear
