DUONCPM+.DOC

The  library  DUONCPM+.LBR  (DU:  on  CP/M  Plus)  contains three
programs which allow one to use du: (disk/user area) syntax  with
the  CP/M+  utilities;  PIP.COM,  DIR.COM and D.COM.  Each of the
three programs are basically simple command  line  parsers  which
read  a  command  line  with the du: format and convert it into a
command line  using  the  traditional  CP/M  d:  format  plus  an
appropriate command line parameter to specify the user area.  The
CP/M+  Chain to Program BDOS call is then used to to execute PIP,
DIR or D with the edited command line tail.

PP#10.COM  chains  to  PIP.COM  3.0.   Its syntax is identical to
PIP's except that source and destinations files may be  specified
in du: format

     PP {du:}desfil = {du:}srcfil1{,{du:}srcfil2,...}{[ooo]}

where  the  o's denote any of the normal PIP parameters (except g
which is no longer required).  All disk and  user  specifications
are optional and the standard PIP defaults are in effect.

DR#10.COM  chains  to  DIR.COM.  Its syntax is identical to DIR's
except that files may be specified in du: format

             DR {du:}filname{[o,o, ..]}

where  the  o's denote any of the normal DIR options (except USER
which is no longer required).  Disk and user  specifications  are
optional and the standard DIR defaults are in effect.

DD#10.COM  chains  to  D.COM  (WHICH  MUST  BE RENAMED DDD.COM to
circumvent  the  "infamous"  CP/M+  CCP  bug).   Its  syntax   is
identical to D's except that files may be specified in du: format

             DD {du:}filname{[o,o, ..]}

where  the o's denote any of the normal D options (except g which
is  no  longer  required).   Disk  and  user  specifications  are
optional and the standard D defaults are in effect.

With  PP,  DR,  and  DD added to the existing repertory of public
domain utilities which support the  du:  format  and  work  under
CP/M+  [NSWP,  NULU,  SD  (later  versions),   TYPEL,  SCAN,  UDE
etc.]  and the ZCPR2 utilities which support the du: format [and,
unlike  the  ZCPR3  utilities,  work  under CP/M+ if one does not
install the ZCPR2 specific  options]  it  is  possible  build  an
entire  library  of CP/M+ utilities which support the du: format.
Moreover, coupled with CCP+ and DIRLN (An  RSX  which  translates
CCP+  directory  names  into the equivalent du: format.)  one can
implement a CPM+ system with full named directory support.

These programs are placed in the public domain for non-commercial
use by R.  SAEKS - 02/12/86.
