Object REXX is a high-level, general-purpose, interpreted, object-oriented (class-based) programming language.Today it is generally referred to as ooRexx (short for "Open Object Rexx"), which is the maintained and direct open-source successor to Object REXX.
When the computer calculates a formula in one cell to update the displayed value of that cell, cell reference(s) in that cell, naming some other cell(s), causes the computer to fetch the value of the named cell(s). A cell on the same "sheet" is usually addressed as: =A1 A cell on a different sheet of the same spreadsheet is usually addressed as:
Until that time, each Microsoft application had its own macro language or automation technique, and the tools were largely incompatible. The first Microsoft application to debut VBA was Microsoft Excel 5.0 in 1993, based on Microsoft Visual Basic 3.0.
The directional-change intrinsic time operator was developed for the analysis of financial market data series. It is an alternative methodology to the concept of continuous time. [1] Directional-change intrinsic time operator dissects a data series into a set of drawups and drawdowns or up and down trends that alternate with each other.
In the language of guarantees, mutable has no guarantees (the function might change the object), const is an outward-only guarantee that the function will not change anything, and immutable is a bidirectional guarantee (the function will not change the value and the caller must not change it). Values that are const or immutable must be ...
When events are instantaneous, activities that extend over time are modeled as sequences of events. Some simulation frameworks allow the time of an event to be specified as an interval, giving the start time and the end time of each event. [citation needed] Single-threaded simulation engines based on instantaneous events have just one current ...
