   Z3VARLIB.REL consists  of  five routines  for manipulating shell variables.
The individual routines are assembled into  a  Microsoft-compatible library of
relocatable (.REL) code  fragments.  ZLINK, LINK80, and  other linkers  can be
used to integrate these routines into your programs.  
     
   Z3VARLIB provides  a convenient and easy way to create ZCPR3 utilities that 
can access shell variables.  The  library  provides  routines  for reading and 
writing the shell variable  file  as  well  as  for  finding  particular shell 
variables and adding and deleting shell variables.   Original version by Dreas
Nielsen (1/87).

 Modules 

          VARLOAD   Loads the shell variable file into memory
     
          VARDEF    Locates the definition for a specified variable
     
          DELVAR    Deletes a specified variable
     
          ADDVAR    Adds a new variable and definition, or redefines an old
                    one
     
          WRTVARS   Writes out the shell variable file


          A sixth PUBLIC symbol in the library is Z3VARS.  The 16-bit value at
this address is  a pointer  to the beginning of  the variable list.  Z3VARS is 
initialized by  the VARLOAD routine, using  the value passed to VARLOAD in HL.
Before the variable list is loaded, the value of Z3VARS will be a binary zero.

 Z3VARS Notes 

   a. Z3VARLIB was originally written  by Dreas Nielsen (1/87).   The routines 
      were  reworked  and shortened  by Howard Goldtsein  (7/89),  but  remain 
      functionally identical  to the originals.   Z3VARLIB is  now distributed 
      with both Microsoft and SLR format REL files.

   Z3VARLIB.HLP is a Z-System help file  explaining the function  and usage of
the Z3VARS routines.  It can be accessed from the Z3HELP-Y.LBR.
