BREAK Command
EDIT Command Summary
058061 Tandem Computers Incorporated 4–29
2. The command:
*BREAK 46 AT WORD "ill"
46 Jack and Jill went up the hill to fetch a pail of water,
*
asks EDIT to break the line at the string “ill” only if “ill” is a word. Line
46 contains “ill” twice, but the string only occurs inside other words.
EDIT, therefore, can’t find a string that matches exactly the string on the
command line, so it returns line 46 unbroken.
