read commands from a file or device
This command executes all CoCoA commands in the file or device named
S. A typical use of
source
is to collect user-defined functions and
variables in a text file, say,
MyFile.coc
and then execute:
source "MyFile.cocoa5";
or, equivalently, the obsolescent
<< "MyFile.cocoa5";
Functions and variables read in from a file in this way will erase
functions and variables with identical names that may already exist.
This can be avoided by using packages. Repeatedly used functions can be
read into CoCoA at start-up by using
source
in the
userinit.coc
file.
