+			JSYS PACKAGE
+			.... .......
+
+	THIS PACKAGE IS A JSYS HANDLER FOR TENEX AND TWINEX MUDDLE.
+THERE ARE TWO RSUBRS, JSYS AND ADR. ALSO THERE IS AN OBLIST CALL J THAT
+HAS THE ATOMS WHO'S PNAMES ARE THE NAMES OF THE 10X JSYS'S. THE GVALS
+OF THESE ATOMS ARE THE RIGHT HALFS OF THE JSYS'S.
+
+	THE RSUBR ADR TAKES ONE ARGUMENT. THIS IS EITHER A STRING OR
+AN UVECTOR. ADR RETURNS A BYTE POINTER TO A STRING OR THE ADDRESS OF
+THE FIRST WORD IN THE UVECTOR.
+
+	THE RSUBR JSYS IS USED TO EXECUTE THE JSYS OF YOUR CHOICE. IT
+HAS FIVE REQUIRED ARGUMENTS (PRIMTYPE WORD) AND AN OPTIONAL SIXTH ONE,
+WHICH IS OF TYPE VECTOR (<VECTOR [2 <PRIMTYPE WORD>]>). THE FIRST ARG
+IS THE THE RIGHT HALF OF THE JSYS TO PREFORM. ARGS 2 - 4 ARE THE ACS
+1 - 3. THE 5TH ARG IS THE ADDRESS OF THE AC TO RETURN. THE SIXTH ARG
+IS AN OPTIONAL TWO VECTOR FOR THE RESALTS TO RETURNED IN. IF THIS
+ARG IS MISSING THEN JSYS PUTS ITS RESALTS INTO THE GVAL OF THE ATOM
+JSYSVECTOR!-IJSYS!-JSYS!-PACKAGE.
+	JSYS RETURNS A TWO ELEMENT VECTOR (<VECTOR WORD FIX>). THE
+FIRST ELEMENT IS THE VALUE OF THE AC POINTED TO BY ARG 5, AND THE
+SECOND ELEMENT IS THE SKIP COUNT OF THE JSYS THAT WAS EXECUTED.
+
+	EXAMPLE 1
+<JSYS ,SOUT!-J
+      <1 .OUTCHAN>
+      <ADR <SET S "THIS IS A TEST">>
+      <- <LENGTH .S>>
+      2>		;"OUTPUT THE STRING .S ON OUTCHAN"$
+
+	EXAMPLE 2
+<SET FOO
+     <CHTYPE <1 <JSYS ,NIN!-J
+		      <1 .INCHAN>
+		      0
+		      10
+		      2>>
+	     FIX>>	;"READ THE NEXT FIXED NUMBER TYPED ON INCHAN 
+			  IN BASE TEN AND SET THE LVAL OF FOO TO THE
+			  NUMBER."$
+
+
+	--- NOTE ---
+THIS PACKAGE OFFERS THE 10X MDL HACKERS HUNDREDS OF WAYS TO SCREW THERE
+CORE IMAGE OF MUDDLE UP, DELETE THERE FILES, OR LOG OUT THERE JOB. 
+BECAUSE OF THIS I TAKE NO RESPONSIBILITY FOR THE USE OF THIS PACKAGE.

+			SUBSYS PACKAGE
+			------ -------
+
+ THIS PACKAGE WILL LET THE TOPS-20 MUDDLE USER EXECUTE ANY 'EXE' FILE
+AS AN INFERIOR TO MUDDLE. AT THE MINUTE SUBSYS IS THE ONLY RSUBR IN THE
+PACKAGE. THIS PACKAGE USES THE JSYS PACKAGE.
+
+ SUBSYS TAKES ONE OPTIONAL ARGUMENT OF TYPE STRING. THE STRING IS THE
+NAME OF THE NAME OF THE FILE TO RUN AS AN INFERIOR TO MUDDLE. THIS ARGUMENT
+WILL DEFAULT TO "<SYSTEM>EXEC.EXE", THUS <SUBSYS>$ WILL RUN THE EXEC.
+SUBSYS RETURNS THE FORK HANDLE OF THE LOWER FORK WHEN IT QUITS. THE
+FORK HANDLE IS OF TYPE WORD AND WILL BE USED BE OTHER RSURS ADDED TO 
+THIS PACKAGE.
+
+		EX. 1.1
+		--- ---
+<SUBSYS>	;"THIS WILL RUN AN EXEC"$
+
+		EX. 1.2
+		___ ___
+<SUBSYS "<MDL>MDL104.EXE">	;"RUN AN INFERIOR MUDDLE"$
+
+
+
+THE RSUBR "CONTINUE" LETS THE CONTINUE A FORK THAT HE QUIT. IT ACTS
+LIKE A $P FROM DDT. CONTINUE TAKES ONE ARGUMENT OF PRIMTYPE WORD.
+THIS ARGUMENTS IS THE FORK HANDLE OF THE FORK TO RESUME. IT SHOULD 
+BE A VALID INFERIOR FORK HANDLE. CONTINUE RETURNS THE FORK HANDLE
+WHEN THE LOWER FORK QUITS.
+
+		EX. 2.1
+		--- ---
+<SET FH <SUBSYS>>		;"RUN AN EXEC AS A LOWER FORK"$
+@;DO SOMETHING
+@POP
+#WORD *400XXX*			;"THIS IS THE FORK HANDLE .FH"
+;"PLAY WITH MDL"
+<CONTINE .FH>			;"CONTINUE THE EXEC"$
+@DIR <FOO>*.* ;DIR OF FOO'S DIRECTORY
+...........
+
+
+
+KILLFORK IS THE RSUBR TO KILL A LOWER FORK, SINCE WHEN YOU QUIT A
+LOWER FORK IT DOESNT DIE. KILLFORK TAKES ONE ARGUMENT OF PRIMTYE
+WORD, THIS IS THE VALID FORK HANDLE OF THE PROCESS TO KILL. KILLFORK
+CAN'T BE UNDONE, ALSO ALL THE INFERIORS OF THE KILLED FORK ARE
+KILLED.
+
+		EX. 3.1
+		--- ---
+
+@; LETS KILL THE EXEC FROM EXAMPLE 2!
+@POP
+#WORD *400XXX*
+<KILLFORK .FH>			;"THE EXEC IS KILLED"$
+#WORD *400XXX*			;"FREE FORK HANDLE. NOT GOOD FOR ANYTHING"

+ The UVBYTES package has now been released to the world, it will work on
+both XXs and ITS. There is  one function in this package, UV-BYTES.  The
+purpose of UV-BYTES is to corrupt  UVECTORs into BYTES of any  bytesize.
+It does this by consing  up a bytpointer of  the requested byte size  to
+the UVECTOR.  Note,  the BYTES  created  UV-BYTES will  shear  the  same
+storage as the UVECTOR. The contents  UVECTOR must be of primtype  WORD.
+The main use  of UV-BYTES  is to  create multiple  windows of  different
+bytesize to the same UVECTOR. The call to UV-BYTES follows.
+
+
+;"UV-BYTES RETURNS BYTES FOR ANY GIVEN BYTE SIZE TO A UVECTOR
+  OF PRIMTYPE WORD. THE CALL TO THIS ROUTINE IS <UV-BYTES .UV .BSIZE>.
+  UV-BYTES RETURNS AN OBJECT OF TYPE BYTES. ARGS ARE:
+  .UV ........ A UVECTOR OF PRIMTYPE WORDS
+  .BSIZE ..... THE BYTE SIZE OF THE DESIRED BYTES, MUST BE LEES THAN 36."
