Procedural macros

Macros in the PL/I accent are accounting in a subset of PL/I itself: the compiler executes "preprocessor statements" at accumulation time, and the achievement of this beheading forms allotment of the cipher that is compiled. The adeptness to use a accustomed procedural accent as the macro accent gives ability abundant greater than that of argument barter macros, at the amount of a beyond and slower compiler.

Frame Technology's anatomy macros accept their own command syntax but can additionally accommodate argument in any language. Each anatomy is both a all-encompassing basic in a bureaucracy of nested subassemblies, and a action for amalgam itself with its subassembly frames (a recursive action that resolves affiliation conflicts in favor of college akin subassemblies). The outputs are custom documents, about compilable antecedent modules. Anatomy Technology can abstain the admeasurement of agnate but cautiously altered components, an affair that has bedeviledcomputer application development back the apparatus of macros and subroutines.

Most accumulation languages accept beneath able procedural macro facilities, for archetype acceptance a block of cipher to be again N times for bend unrolling; but these accept a absolutely altered syntax from the absolute accumulation language.
