2.7.1. Introduction to IO |
Input and output is implemented in CoCoA through the use of "devices." At present, the official devices are: 1) standard IO (the CoCoA window), 2) text files, and 3) strings. What this means is that it is possible to read from or write to any of these places. The cases are discussed separately, below. Text files may be read verbatim or---with the 'Source' command---be executed as CoCoA commands. |
