The purpose of this function is to print the string S without
scrolling off of the screen.
The first form of this function stores the string S in a 'MoreDevice',
then prints the first N lines from the MoreDevice where N is the
integer stored in the global variable MEMORY.MoreCount. Subsequent
calls to 'More' print the next N lines from the MoreDevice, (each time
removing the lines from the device) until the MoreDevice is empty.
After each call to 'More' a line with 'More();' is printed as long as
the MoreDevice is not empty. This line is easily cut-and-pasted.
The user may set the number of lines to print with the command
'MEMORY.MoreCount := X', where X is an integer. The default is value
is 20.
If E is *any* CoCoA object, the command 'Sprint(E)' converts E into a
string. The output may then be given to 'More' for printing.
To use the more device with the online help system, see
'H.SetMore, H.UnSetMore'.
