Abstract: STAGE2 is a general purpose macro processor designed by

W. M. Waite, and may be used as a front end to other languages such as

SABR, FORTRAN and BASIC. Device independent I/O, and access to

several files allows for flexible processing and multiple passes within the

macro processor. Macro calls are recognized by a pattern matching

scheme that allows for flexible syntax in macro definition. The special

characters controlling the macro processor may be easily defined so that

they do not interfere with the host language. Handles upper and lower

case, and control characters. STAGE2 is itself written in a language

(FLUB) that is translated by STAGE2 into PAL-8.
