You want this w/o the if? I think you can write:

> @quantities = map { if (/^=/) { s/\D//g; '=' . $_ } else { s/\D//g; $_ } }

@quantities = map { s/(^=)?\D/$1/g; $_ }

or better:

@quantities = map { s/[^\d=]//g; $_ }

or maybe faster like:

#delete unknown (==not 0-9,=) chars and map something(?):
@quantities = map { tr/0-9=//cd; $_ }

all this is untested, and my perl will not even compile your
original expression, which I do not understand BTW, since I
though that map should get some list as second argument (to map
that list), so this seems to be some special usage of map or
whatever. :)


oki,

Steffen
