Also you could try (assuming you have perl, which you should):

perl -pi -e 's/ memmast / wk_memmast /' memmast.dmp

to replace all occurances in the file w/o making a copy.

And:

perl -pi -e 's/CREATE UNIQUE INDEX /CREATE UNIQUE INDEX wk_/' memmast.dmp
perl -pi -e 's/CREATE INDEX /CREATE INDEX wk_/' memmast.dmp

It looks like you've got the idea anyway. There are ways to get even fancier
with the perl tool, but for now keep it simple and have fun with it.
