fold    --    inset newlines into a long string


Syntax 
fold(S: STRING, W: INT): STRING

Description
This function copies a string inserting a newline every W characters. Together with sprint it can be helpful for displaying a long result more comprehensibly. Also Emacs can become quite slow if there are long lines in the output: combination of sprint and fold can help in such cases.

Example 
/**/  n := factorial(100);
/**/  fold(sprint(n), 60);
