Interaction mechanisms with global variables are called global environment (see also global state) mechanisms. The global environment paradigm is contrasted with the local environment paradigm, where all variables are local with no shared memory (and therefore all interactions can be reconducted to message passing ).
Code written in VBA is compiled [6] to Microsoft P-Code (pseudo-code), a proprietary intermediate language, which the host applications (Access, Excel, Word, Outlook, and PowerPoint) store as a separate stream in COM Structured Storage files (e.g., .doc or .xls) independent of the document streams.
In most implementations, many worksheets may be located within a single spreadsheet. A worksheet is simply a subset of the spreadsheet divided for the sake of clarity. Functionally, the spreadsheet operates as a whole and all cells operate as global variables within the spreadsheet (each variable having 'read' access only except its containing ...
Macros in PL/I, as well as in many assemblers, may have side effects, e.g., setting variables that other macros can access. Frame technology's frame macros have their own command syntax but can also contain text in any language. Each frame is both a generic component in a hierarchy of nested subassemblies, and a procedure for integrating itself ...
Since the Leszynski naming convention is a special form of Hungarian notation the same general advantages also apply to the Leszynski convention.. The use of distinctive prefixes makes your database self-documenting; when you see frmSales in VBA code, you will know that it references a form, and when you see curSales you will know that it is a Currency variable.
In languages compiling down to .NET platform, types are strict. Whilst the runtime allows for anonymous object which don't have a pre-defined, named type, the type of a variable may not change over the course of its life-time, hence the need to drop the Variant data-type. However, type "Object" has somewhat similar behavior in practice.
This is a module definition. Modules are a division of code, which can contain any kind of object, like constants or variables, functions or methods, or classes, but can not be instantiated as objects like classes and cannot inherit from other modules. Modules serve as containers of code that can be referenced from other parts of a program. [8]
Other excluded features include the removal of support for third-party code such as macros/VBA/ActiveX controls, the removal of support for older media formats and narration in PowerPoint, editing of equations generated with the legacy Equation Editor, data models in Excel (PivotCharts, PivotTables, and QueryTables are unaffected), searching ...
