in reply to Need help making the change to OO

I do not think that you are really trying OO here ... but if you want to "wrap your head around it," it's simple. (Especially in Perl, which "keeps the useful ideas well a hand and skips the academic-only stuff.") An object is a chunk of data which has a chunk of executable code "somehow, magically" associated with it ... such that when you do, "hey you! do this!" the computer can figure out on its own how to "do this." It figures out on its own which subroutine to call. The subroutine that gets called can figure out who "you" is. The key advantage is that the language figures out, on-the-fly every-time right-now at runtime, exactly how to tell "you" to do "this."somehow, magically

[james28909]: how can i write a while loop on one line (in a script) something like print "this\n" && print "that" && <DATA> && print the other\n" && next if /this matches/ while <DATA>?
[james28909]: i have tried with && and and and have tried to rearrange the functions as well to no avail
[shmem]: use parens to group expressions
[shmem]: you can't use next in a statement modifier
[shmem]: next requires a BLOCK
