elisp - inserting block of text

[Gary]

What function(s) do I need to use in order to insert some text, please? 

I know about 'insert', but am wondering how I would go about inserting
line breaks, for example, when the buffer might contain a file with *n*x
or DOS line endings, or even a mix of the two.

(insert "foo\nbar\n") inserts foo and bar, and after each one the right
newline, carriage-return, or both, depending on the buffer's coding
system.

The _buffer_ never contains any line endings but the Unix ones.  The
_file_ that is visited by the buffer could have any style of line
endings and even a mix of them, but a buffer cannot.

No, it always insert a single newline.  The buffer's coding system is
only important when the buffer is saved to its file.

Good to know.  But in end, what only matters is that Emacs DTRT. :-)
