Go to the documentation of this file.

/* vixie.h - include file to define general vixie-type things
 * v1.0 vix 21jun86 [broken out of as.h]
 */

/*
There are two macros you can define before including this file which can
change the things defined by this file.
    
DEBUG: if defined, will cause enter / exit messages to be printed by the
ENTER / EXIT / EXITV macros. If not defined, causes ENTER to do nothing, and
EXIT / EXITV to generate 'return' without any messages. If defined, should
be set to the name of the including module.

MAIN: Should be defined for a program containing a main() function which is
linked with other modules which include this file. Value is not important,
only existence / nonexistence matters.
