Unix developers already have a built-in macro processor, in the form of the C preprocessor, in their compiler. Perhaps this is what accounts for m4’s relative neglect.

However, the macro processor does not store the macro for execution. A macro that the macro processor compiles but does not store is called a dummy macro. Macro APP in the Input Stack. In this example ...

The macro processor looks in the local APP symbol table and resolves the macro variable reference &GOAL to 10000. the macro processor places the value on top of the input stack, ahead of the remaining ...

Like cpp, m4 originally was written as the pre-processor for a programming language (Rational FORTRAN); however, m4 is much more powerful and feature-rich than cpp, which makes it much more useful ...

It’s a robust macro processor that swaps out all of her macros based on a separate file which defines them. The result is an assembly file that will play nicely with avr-as.

Among its thousands of features, macros are power-user tools that could benefit a lot of people. You hit Record Macro, you do something — a search and replace, let’s say — and then you can ...

Scalar means a single value, as opposed to a vector.A vector processor takes a vector of values, say 10 14 666 22 84 53 45 25 14 47 91 and with 1 instruction performs the same operation on all of ...

(1) A special-purpose command language used to automate sequences within an application such as a spreadsheet or word processor. Macro languages often include programming controls (IF THEN, GOTO ...

The processor uses up 15,300 transistors and 8,500 LED’s, while the RAM has 27,000 transistors and 2,048 LED’s.””” For each bit you need 2 transistors, so 16 per byte.
