Lower->Upper in AWK (was: Re: cascading pipes in awk)

[Gunter Steinbach]

    This may make awk purists wail, but why not use:

    awk 'some stuff;
	some condition {print | "tr [a-z] [A-Z]"}' |
    awk 'other stuff'

    It works, albeit slow due to two awk calls, but it saves a lot of typing
    over some of the other suggestions.
