in reply to IPC::Open3: differences among replies of a background process

It might be about Window's non-POSIX primary interface. Maybe the interactive commands are using some APIs that IPC::Open3 isn't going to be able to cope with. You might want to consult MSDN. Maybe there's something like strace but for Windows.

[Your Mother]: They would think so.
[jdporter]: ok, I need a recipe for piping lines "through" an external program which is itself a filter
[jdporter]: without using a tmp file
[1nickt]: tobyink perl -MTypes::Standard= is_Int -Mstrict -wE 'say 1 if is_Int 1.0'

[LanX]: jdporter: open PIPE,'-|' ?
[LanX]: oh you want the result line by line?
[jdporter]: ok, LanX, then what?
[jdporter]: It doesn't have to be line by line. Just "my program" "writes" to the external prog and also/then "reads" from it.
