9.8 Macros (Compile-Time Procedures)

Macros are objects that a language processor replaces with other text during compilation. Macros are great devices for replacing long, repetitive sequences of text with much shorter sequences of text. In additional to the traditional role that macros play (e.g., #define in C/C++), HLA's macros also serve as the equivalent of a compile-time language procedure or function. Therefore, macros are very important in HLA's compile-time language—just as important as functions and procedures are in other high-level languages.

Although macros are nothing new, HLA's implementation of macros far exceeds the macro-processing capabilities of most other programming languages (high level or low level). The following sections ...
