open a log of a CoCoA session
***** NOT YET IMPLEMENTED *****
This function opens the output device D and starts to record the
output from a CoCoA session on D. The
CloseLog
closes the
device D and stops recording the CoCoA session on D.
At present the choices for the device D are an output file (see
OpenOFile
) or an output string (see
OpenOString
). Several output
devices may be open at a time. If the panel option
Echo
is set to
True, both the input and output of the CoCoA session are logged;
otherwise, just the output is logged.
D := OpenOFile("MySession");
