WebSpeed preprocessors

The preprocessor is a function of the ABL compiler that also applies to SpeedScript. On its initial pass through source code, the compiler looks for preprocessor directives and performs text substitutions when it finds them. All directives begin with an ampersand (&).

The WebSpeed preprocessors, which are listed in the following table, provide consistent access to the Web environment, especially the Web output stream. The definitions of WebSpeed preprocessor names reside in install-path/src/web/method/cgidefs.i.
