The STEP Preprocessor

Show all headers | View raw

Many years ago I worked with the STEP Preprocessor.

It was first described to me as a form of Compiler-Compiler,
but it seems more like a Preprocessor-Compiler.  (It runs more
like an interpreter than is usual for a compiler.)

In case anyone is interested, the manual is now online at:

http://www.bitsavers.org/pdf/stanford/slac/The_STEP_Processor.pdf

Unlike many preprocessors, the macro form can describe the
exact grammar required, process appropriately or print error
messages, and generate any required output.

I now have the source code (in Fortran-66, and in an extended
Fortran processed by STEP macros.)  I hope soon to send it to
the software archive of bitsavers.

Not that I follow preprocessors so carefully, but I don't know
of anything at all similar done since then (about 1977).
