This shows the typical layout of a simple computer's program memory with the text, various data, and stack and heap sections. Historically, BSS (from Block Started by Symbol) is a pseudo-operation in UA-SAP (United Aircraft Symbolic Assembly Program), the assembler developed in the mid-1950s for the IBM 704 by Roy Nutt, Walter Ramshaw, and others at United Aircraft Corporation.
A macro assembler is an assembler that includes a macroinstruction facility so that (parameterized) assembly language text can be represented by a name, and that name can be used to insert the expanded text into other code. Open code refers to any assembler input outside of a macro definition.
However, the macro facilities of more sophisticated assemblers, e.g., IBM High Level Assembler (HLASM) can't be implemented with a preprocessor; the code for assembling instructions and data is interspersed with the code for assembling macro invocations. A classic use of macros is in the computer typesetting system TeX and its derivatives ...
X macros are an idiomatic usage of programming language macros for generating list-like structures of data or code. They are most useful when at least some of the lists cannot be composed by indexing, such as compile time. They provide reliable maintenance of parallel lists whose corresponding items must be declared or executed in the same order.
the high degree of re-expansion (a macro's arguments get expanded twice: once during scanning and once at interpretation time) The implementation of Rational Fortran used m4 as its macro engine from the beginning, and most Unix variants ship with it. As of 2024 many applications continue to use m4 as part of the GNU Project's autoconf.
There are similar hacks to the marshmallow method using a slice of bread (same principle, but using the moisture from white bread instead). This is a completely fine swap for marshmallows. Just ...
By John Revill. BERN (Reuters) - Switzerland said on Tuesday it was concerned by U.S. President-elect Donald Trump's proposals to raise tariffs and is considering how to respond if his new ...
the use of 2 to check whether a number is even or odd, as in isEven = (x % 2 == 0), where % is the modulo operator; the use of simple arithmetic constants, e.g., in expressions such as circumference = 2 * Math.PI * radius, [1] or for calculating the discriminant of a quadratic equation as d = b^2 − 4*a*c
