CoCoA:More

More

print a string, N lines at a time

Description

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.
