Question Pattern to replace ^M and ^Y in a 4.2 AIX text file

I have files on my AIX 4.2 client system where I need to do the following replacements below but have no clue how ? They are control characters (linefeed, chariage return, ...).


First, replace "^M^Y^M" with ^char_for_end_of_line
Then replace "^M" with " "
Trim all left spaces

In VI, my files contents look like this :

aaaa zzzzzzzzzzzzzzzzzzzzzz^M
zzzzzzzzzzzzzzzzzzzzzz^M
zzzzzzzzzzzzzzzzzzzz^M
^M
^Y^M
aaaa zzzzzzzzzzzzzzzzzzzzzz^M
zzzzzzzzzzzzzzzzzzzzzz^M
zzzzzzzzzzzzzzzzzzzz^M
^M
^Y^M
aaaa zzzzzzzzzzzzzzzzzzzzzz^M
zzzzzzzzzzzzzzzzzzzzzz^M
zzzzzzzzzzzzzzzzzzzz^M
^M
^Y^M
...

I want it to be:
aaaa zzzzzzzzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzzzzzzzz
aaaa zzzzzzzzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzzzzzzzz
aaaa zzzzzzzzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzzzzzzzz
aaaa zzzzzzzzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzzzzzzzz
aaaa zzzzzzzzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzzzzzzzz
...

Nb of records is unknown.
'zzzzzz' can have any combinations of "(", ")", "'", """, ",", "[", "]", ".", ";" (in other words anything with printable characters)
