This is the same usage for the "sed" command-line command. Here's the sort
of mnemonic I use to remember it:
sed 's/this/that/g'
_s_tream _ed_itor, 'like _s_ubstitute / this [with] / that / _g_lobally'
(I used to think of the "g" as "_g_ood, now we're done" back in 1994ish.)

Those www.ora.com books are quite pricey, and the catch-22 of it all is you
don't want to wait for the price to drop with time or buy an older used
copy because (except in the case of regexp, for example) the current
applications obsoletize :)
