I'm reposting this due to Net problems reported to me by SRI.

I'm trying this request for help one more time. My first request yielded
no responses...
I need to know several things about advanced programming in ACTION! :
 
	1) Is it possible to "chain" ACTION! programs (load in and
	   execute a new program at termination of first program).
 
	2) Is it possible to invoke the ACTION! compiler from within
	   a program. (lets say that I have a source file on disk
	   and I wish to have a program invoke the compiler to 
	   compile the file from disk into memory). All you 
	   probably need is the entry point that the ACTION! monitor
	   calls when you type the "C" command; as well as knowing
	   where this routine expects to find the file name.
 
	3) Is there some magical document that explains the above
	   and other mysteries (e.g. symbol table format ...)
 
Please (!!!!!!) reply with ANY information to me at the following
address.

The following is from the OSS bulletin board, (408) 446-3451.
It may require use of their DOS XL. I haven't tried it.
