They are created by carrying out the sequence once and letting the application record the actions. An underlying macro programming language, most commonly a scripting language, with direct access to the features of the application may also exist. The programmers' text editor Emacs (short for "editing macros") follows this idea to a conclusion ...
As an example, VBA code written in Microsoft Access can establish references to the Excel, Word and Outlook libraries; this allows creating an application that – for instance – runs a query in Access, exports the results to Excel and analyzes them, and then formats the output as tables in a Word document or sends them as an Outlook email.
Alternatively, the file might not exist, or the user has mistyped its name. This is most commonly seen on the internet with outdated links to web pages that no longer exist. On a local computer, this is more frequent on command line interfaces than on graphical user interfaces where files are presented iconically and users do not type file names.
It also introduced the ability to write non-GUI classes in Visual Basic. With VB4 the language was separated from the GUI library, and made available as VBA, in which form it was embedded with the Office 95 suite. To ease migration of Office macros and scripts, features from WordBasic, Excel Basic and Access Basic were incorporated into the ...
Upon leaving the using-block, the compiler guarantees that the stm object is released, effectively binding the variable to the file stream while abstracting from the side effects of initializing and releasing the file. Python's with statement and Ruby's block argument to File.open are used to similar effect.
Access, the successor to ENGLISH, is an English-like query language used in the Pick operating system.. The original name ENGLISH is something of a misnomer, as PICK's flexible dictionary structure meant that file and attribute names could be given aliases in any natural language.
C does not provide direct support to exception handling: it is the programmer's responsibility to prevent errors in the first place and test return values from the functions.
8 File name and extension — together these form a 8.3 file name. 0x09 3 0x0C 20: Implementation dependent — should be initialised to zero before the FCB is opened. 0x20 1: Record number in the current section of the file — used when performing sequential access. 0x21 3: Record number to use when performing random access.
