PUTMSG port_description [number1|string1] [number2|string2] ...

* PUTMSG is useful for testing programms which wait for a message,
  or to reactivate a task that waits for a message which will never
  arrive. PUTMSG sends a message to the given messageport.
* port_description can be given in 5 (!) ways:
  - Name of the messageport
  - Adress of the messageport
  - 3 ways of a task_description, see  BREAK . This MUST be a Process
    because the process-internal messageport will be used.
* number|string is a longword number or a string. If it is a number,
  it will just be added to the message. If it is a string, a
  adress pointing to this string will be added to the message.
  If number1|string1 was a point (.), the message will be initialized
  as an DOS-Packet.
* After sending the message PUTMSG will wait for the reply and show
  that reply like  GETMSG . Abort waiting with CTRL-C.
WARNING: Your machine might CRASH if you send a message to a
  (Process-internal) port that is not waiting for this message.
NOTE: PUTMSG without arguments makes a DisplayBeep (even without a
  window) and outputs the internal register value of A5.

eg.     putmsg testtask $21fd68 12
        putmsg testport "Hello World!"

  If you have 2 ZShells, execute in the one with CLI-number 1
  "getmsg". Activate the other shell and type
        putmsg 1 "like some chatting ?"
  The ZShell no. 1 should display that and prompt "reply ?". Answer
  "y" and the message goes back again.
  Now try "getmsg wurgutz" at one ZShell and "putmsg wurgutz $abcd"
  on the other. Do not forget to reply.

* You can use PUTMSG to use the AREXX interface of a programm. This
  works with some programms even with OS1.3- and no AREXX-Package.
eg.     putmsg showdvi 0 0 0 0 0 "tofront" {gets ShowDVI to front}
  Instead of the first 0 you sometimes must write the adress of
  this task. If available replace the second 0 with a pointer to
  the rexxsyslib.library. The third 0 is called rm_Action. I do not
  know what it is for. The fourth and fifth are results, only
  interesting in the reply.
eg.     putmsg showdvi 0 0 0 0 0 "loadnew tex.dvi"

* Specify a point as first number if you want to send a DOS-Packet.
eg.     putmsg DF0 . 0 1023 0 0 -1     {same as LOCK DF0: ON}
  If you get $FFFFFFFF as 4th longword, it was successful.
 (with OS1.3- you need to use FileSystem instead of DF0)
