Pressing the Scroll Lock key in the Linux console while the text is scrolling through the screen freezes the console output (but not input) during which no further text is sent to the screen, while the program continues running as usual, or become blocked at the write syscall when too much data prevented from reaching the terminal caused the tty's output queue to become full and the tty file ...
A plain text text entry form, by contrast, may use a simpler method, setting a fixed and arbitrary display width within which the caret always ‘wraps around’, only scrolling up or down a line as the caret reaches the wrap point at the start/end of the current first/last line, in order to keep the edit point in view as it moves to the ...
Microsoft confirmed this week that it will soon start blocking Visual Basic Applications (VBA) macros in Office apps by default after quietly rolling back the change earlier this month. In a new ...
The ability to use a familiar procedural language as the macro language gives power much greater than that of text substitution macros, at the expense of a larger and slower compiler. Macros in PL/I, as well as in many assemblers, may have side effects, e.g., setting variables that other macros can access.
Macros could examine system data, make decisions, be chained together, and operate recursively until a defined "stop" condition occurred. This capability provided a powerful way to rearrange data and formatting codes within a document where the same sequence of actions needed to be performed repetitively, e.g., for tabular data.
Scrolling may take place in discrete increments (perhaps one or a few lines of text at a time), or continuously (smooth scrolling). Frame rate is the speed at which an entire image is redisplayed. It is related to scrolling in that changes to text and image position can only happen as often as the image can be redisplayed.
A general-purpose macro processor or general purpose preprocessor is a macro processor that is not tied to or integrated with a particular language or piece of software.. A macro processor is a program that copies a stream of text from one place to another, making a systematic set of replacements as it does so.
Marquee can be distracting. [1] The human eye is attracted to movement, [2] and marquee text is constantly moving. As with the blink element, marquee-tagged images or text are not always completely visible on rendered pages, making printing such pages an inefficient (if not impossible) task; typically multiple attempts are required to capture all text that could be displayed where messages ...
