DATA - Inline Declaration
... DATA(var) ...
A declaration expression with the declaration operator DATA declares a variable var used as an operand in the current writing position. The declared variable is visible statically in the program from the location DATA(var) and is valid in the current context. The declaration is made when the program is compiled, regardless of whether the statement is actually executed.
The declaration operator DATA can be specified in every compatible declaration position. The date type of the variable is determined by the operand type. It must be possible to derive this type statically in full.
A variable var declared inline cannot be used in a reading position of the same statement.
