Updating using explicit cursors

The print statement is convenient for testing because it automatically converts int and other primitive values to strings for display. The Note: The best practice is to use double quotation marks for any string that might be displayed to the user. There is a node titled Jobs in the Application Object Tree (AOT). The following C# program is a rewrite of the previous X program.

This sample can be added under the Jobs node, and then the job can be run. The differences between X and C# are highlighted by commenting out the X lines, and replacing them with the C# syntax. But an int variable that is decorated with can only be used as a statement, not as an expression.

In X , the single quotation marks are not treated as delimiters unless the string starts with a single quotation mark delimiter.

In C# the single quotation mark has no special meaning for strings, and it cannot be used to delimit strings.

For more information, see Best Practice Performance Optimizations: Swapping Arrays to Disk.

An X array can have a dynamic length that can be increased even after population has begun.

In C# the single quotation mark is the required delimiter for literals of type There are similarities and differences in the features and syntax for arrays in X versus C#.

Overall there is much similarity in the syntax and treatment of arrays in X and C#. The following table lists areas in the [] syntax for arrays that are different for X and C#. However, there is advanced syntax for limiting the amount of active memory that a large array can consume, which looks like the multi-dimensional syntax in C#: int int Array[1024,16];.

For class types, X can get no more specific than whether the type is a class (Types:: Class). There are some similarities but many differences when we compare exception related behavior between X and C#.

The while keyword supports looping in both X and C#.

The console output from the C# program is as follows: 1 (Press any key to resume.) 2 (Press any key to resume.) 3 (Press any key to resume.) 4 (Press any key to resume.) (Press any key to resume.) In both X and C#, the switch statement involves the keywords case, break, and default.

However, it is convenient delimit a string with single quotation mark characters when your string must contain a double quotation mark character.

statement is always useful shortly after a print statement.
