in thread Reverse Function

jeffa's answered the question, but , to indulge in a little golf, it can be done in one line :
print reverse map {s/oldpage/newpage/g; $_} <DATA>;

    Well, if you're gonna golf... ;^)

    s/oldpage/newpage/g, print for reverse <DATA>; # 46 s/oldpage/newpage/g,print for reverse<DATA> # 43


      I know, it was discussed here many times, but golf section would be really nice place here, and it's pity it's missing!

[stevieb]: atcroft: "Make both hands into fists..."... is something my Ma taught me in our native lang, but I was to ignorant and young to pay attention. Thanks for that :)
[atcroft]: stevieb: Sad to say that I only recently learned that particular trick, but I have since found it very useful.... :)
[james28909]: ill be back with a solution eventually
[stevieb]: it's a reminder to re-inforce it :P
[atcroft]: james28909: That particular questions was a bit of trick, actually (depending on the country you are in). More interesting is, if you are trying to subtract from an epoch time, for instance, you might have to consider when/if DST occurs for a location,
[atcroft]: because you may have to adjust the number of seconds you change from an epoch from 86400 (not to mention leap seconds)....
[atcroft]: james28909: Although if your program is using a database, you might be able to "pass the buck" to the database and ask it to do the date change for you....
