The NeXT computer on and for which this program has been developed is an acquisition from a CONACYT grant, which must have been one of its more productive investments, given that the computer has been in daily use for many hours since its acquisition.
The program REC/C described in the document can hardly be expected to be error free. Moreover, if it is successful, it will be subject to user demands for improvements, corrections, and assorted changes. Not all of them will necessarily be reflected back in this manual, which is intended more to explain the program than to give a verbatim documentation.
