User Guide

When you read a file with the read command, Maple treats each line in the
file as a command. Maple executes the commands and displays the results
in your document but it does not, by default, insert the commands from the
file in your document.
For example, the file ks.tst contains the following Maple commands.
S:= n -> sum( binomial( n, beta ) * ( ( 2*beta )! / 2^beta - beta!*beta ),
beta=1..n );
S(19);
When you read the file, Maple displays the results but not the commands.
>
If you set the interface echo option to 2, Maple inserts the commands from
the file into your document.

S:=n->sum(binomial(n,beta)*((2*beta)!/2^beta-beta!*beta),beta=1..n);
> S(19);
