Whether this i sthe best way of doing this is an open question, but to pass your array in 200 element chucks, you could use splice. I'm assuming that select_ids() returns a reference to an array.

launch_background( 'glim.exe', 'glim', join' ', splice( @$ids, 0, 200 ); ) while @$ids;

This will consume the array. If you need to retain the array then make a copy. If the array is big and copying costs too much memory then you would need to use a slice and a pointer.

launch_background( 'glim.exe', 'glim', join' ', @{ $ids }[ $_ .. ( $_ + 200 ) ] ) for map $_ * 200, 0 .. int( @$ids / 200 );

You will probably need to add a little logic to the calculation of the upper bound of the slice to prevent "Uninitialised values" warnings unless your array is a multiple of 200.

If I understand your problem, I can solve it! Of course, the same can be said for you.

to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
