While Loop

'while' is a looping attribute which is used to perform a set of instructions until a given condition is satisfied.

SRON provides 'while' attribute to work on while loop. To provide a condition, 'condition' attribute is used.

Syntax of 'condition':

condition :  conditional_value

Examples:

Correct Syntax:
    condition : false
or
    condition : true
or
    condition : ~{ val != 10 }~

---------------------

Wrong Syntax:
    condition : ()
or
    condition : (true)
or
    condition : ([1,2,3,4,5])

'condition' attribute requires a 'Bool' type value, if a 'Bool' type value is not found, then error/exception will be thrown.

    while : {
        condition : ~{ i < 15 }~

        if : {
            condition : ~{ i % 2 == 0 }~
