Anway: an array only becomes false when it's empty. while (@array) will either not loop at all if the array is empty or loop forever until the array is empty.

while (<filehandle>) is a special case. all other construct with while(something) just test if something is true.

Well, it's only special in that it's silently twiddled into while( defined( $_ = <filehandle> ) ) { ... }; it otherwise is still looping until the value of the expression is false (the twiddling being done so that lines that would otherwise be interpreted a boolean false (e.g. 0\n) are differentiated from the diamond-operator-returns-undef-on-eof false value).</pedant>

Yeah that why i used it in the 1st place while (<filehandle>) read a file line be line and only went false if there were no ther lines left so it escaped the llop

while (@files) i believed would do the same thing as while (<filehandle>) did, except from insteading of reading a file line-by-line up ot the end i thought it would read an item-by-item over @array until the end of items and then go false.

perl -e 'print "$_\n" while (1,2,3,4)'

I got this error myabe because iam on windows

C:\Documents and Settings\nik>perl -e 'print "$_\n" for (1,2,3,4)'
Can't find string terminator "'" anywhere before EOF at -e line 1.

even if i switch single quotes with double quotes iam still getting erros.

I used the foreach statement finally.

You say while loops over na @array while it is true.(evaluated as a boolean)? what do you mean?

iterate!= loop ? I was picturing the statement while(@files) as loop over the array as long as it has items in it, and i though it was escaping after the last one.
