Re^3: Need to count the number of entries in a array

~~Please tell me what a better formulation is?~~

~~my ($title, $image, $counter...,@inventory) = map{chomp}<THEFILE>~~

Ok, I made a simple mistake, and one that is common: map{chomp} should be map{chomp; $_} The return from map is the last statement, here $_ is chomped and that result, the chomped version of $_ should be the last statement.

Thanks for pointing this out!

Don't guess. Try it out, or read the documentation for chomp. I've made that mistake before with map and it's a head-scratcher the first two times. (It returns—depending on the line endings of the file—a bunch of copies of `$/`.) Improve your skills with Modern Perl: the free book.	[reply] [d/l]

Most of "us", including the OP, don;t need telling. You could look it up. Or even try your fascile suggestions out, before advising the use of broken code as a replacement for perfectly fine, working code.	[reply]

Fascile: (esp. of a theory or argument) Appearing neat and comprehensive only by ignoring the true complexities of an issue; superficial. My simple error was easily corrected by three characters: ";$_" -that is superficial. My response was not superficial. To the contrary, I offered concrete advice directly related to the problem that did not ignore the complexities.	[reply]
