InFile
InFiles are used to generate user input to automate operations.  The TempleOS 
tour is done with an InFile.  It reminds me of a Unix pipe because StdOut of one 
gets chained into StdIn of another.

When an InFile runs, a child task is Spawn()ed which intercepts real user input 
and generates fake input.  InFiles are HolyC programs run by the child whose 
stdout goes to the parent's input buffer.  Msg() can be included in an InFile to 
send special keys or mouse cmds to the parent.  While an InFile is running, the 
normal input gets diverted to the InFile task and can be filtered and sent back 
to the parent task.  Unless you are driving functions which prompt for data, you 
can probably use an #include file in place of an InFile.

See ::/Demo/InFile/InDir.IN.

Note: In("") can be used if all you need is to send ASCII characters.  It 
differs from InStr().  You'll probably use In() a lot and not InStr().  With In(
), for example, you can place answers to the prompts for recompiling the Kernel 
module during BootHDIns().
