Hello,

My last little improvements were made under BlackBox (see Helmut Zinn's 
site). But the latter example works easily under Oberon: in Regul.Panel, 
write

	$ .* cat (.|$)* dog .*

in the Find: field; write nothing in the Repl.: field; mark (F1) the 
text that must be changed; press Find Next and, then, Replace. It's all.

Hint: $ stands for EOL, a dot (.) stands for any character, but not EOL, 
the star (*) marks the repetition of the previous word, a vertical bar 
(|) stands for a logical OR and braces group expressions together. Press 
the Help button and follow the links in the title for further explanations.

Hint 2: If the first line to be deleted is the first line in the text, 
without any EOL before, don't write the first $ in the Find: field.
