A variable declaration does not specify an As clause.An As clause identifies a data type to be associated with a programming element. In a Dim Statement (Visual Basic), it specifies the data type of the variable or variables. If you do not include an As clause in the Dim statement, the...
Variable names should not contain any reserve keywords like int, char, float and so on. The syntax for variable definition in C# <data_type><variable_name>;<data_type><variable_name>=value;<access_specifier><data_type><variable_name>=value; ...
Just as with normal variables, the act of declaring a default makes it optional; there is no need for an "optional()" keyword/function and conversely not specifying a "default" makes it a required item. Thinking about it, the "object()" declaration could become redundant too, as the fact...
The host-variable definition may either precede or follow a DECLARE VARIABLE statement that refers to that variable. FOR BIT DATA Specifies that the values of the host-variable are not associated with a coded character set and, therefore, are never converted. The CCSID of a FOR BIT DATA ...

If the block contains some parameters, the declaration of the temporary variables must follow the declaration of the parameters. The block: [:x :y | | temp | temp := x squared + y squared. temp squared] has two parameters, variables x and y, and a temporary variable, temp. All these...
