APL\11 circa 1977
This code and documentation has been placed here so that it does not get lost forever.
Note that this version is written in pre-K&R C and will probably not compile with any modern C compiler.
I worked on a similar version of APL\11 in the mid 1970s and was able to get it to compile and work with an early 1980s vintage K&R C compiler. (I had to replace a =+ 1; by a += 1; but otherwise it ported easily)
Read crm.pdf and arrow.pdf for
more background and information on pre-K&R C.
