Bla-handler

A quick & dirty port of Gerhard Mueller's bla-handler program
(http://aminet.net/package/util/cli/BlaDevice10).

Installation:

1. copy bla-handler to L:
2. copy BLA to DEVS:DOSDrivers or SYS:Storage/DOSDrivers

If you copied the BLA file to Storage then you will have to mount the device
manually by entering "mount bla:" on the command line.

   NAME
     BlaDevice - small device that simulates the output of a file
                 as a file


   SYNOPSIS
     "Bla:<CLI-command with parameters>"


   DESCRIPTION
     BlaDevice is a small device that simulates the output of a program
     as a true file.

     Examples:

          type "bla:dir ram:"

          sort "bla: list ram: dirs lformat %N" to ram:y


     If you want to use arguements with '"', you can use *", e.g.:

          sort "bla:list ram: dirs lformat *"(DIR) %N*"" to ram:y


     Bla-device executes the given command asyncronly with the
     given parameters. The output of the command is linked to
     PIPE:<unique name>. This file is used to satisfy the read
     commands of the program that uses BLA:.

     If the using command closes the file before all data is read,
     BLA reads as much as it can read before it closeses the
     PIPE:<unique name> file.

     The following AmigaDos packets are supported:

        ACTION_FINDOUTPUT
        ACTION_FINDUPDATE
        ACTION_READ
        ACTION_END
        ACTION_DIE

   USAGE

     "Bla:<CLI-command with parameters>"


   BUGS
     none known (yet)


   VERSION
     1.0 - initial release


   COPYRIGHT
     BLA-device is full PD. You can do with it what you want. Bla
     device is "as is", THERE IS NO WARRANTY AT ALL. etc. etc.


   BACKGROUND
     BLA device was written mainly because the Amiga shell has no
     real piping. With BLA a lot of tempory files can be made
     obsolete, and the length of the temporary file is not limited.
