CSAP is composed of 4 modules;  CSAP.C, SORTDIR.C, ISDEV.C.C, and 
GETDPB.C.  The  current  version  of  CSAP,  CSAP 2.06,  has been 
designed for compilation with  Borland  International's  Turbo  C 
1.0.  The  module  ISDEV.C.C  could  be  replaced  by  Turbo  C's 
supplied function isatty(),  however,  I plan to extend ISDEV.C.C 
to  distinguish  among  files,  CON,  AUX,  and the printer.  The 
function  isatty()  just  distinguishes  between  files  and  the 
others.  

GETDPB.C cannot be compiled in Turbo C's interactive  environment 
(TC).  It  is  primarily  inline  ASM  code and requires the more 
conventional environment provided by Turbo C's TCC command.  As a 
result,  CSAP was designed to be compiled through the  use  of  a 
MAKEFILE and the MAKE facility of Turbo C.  

CSAP currently compiles and executes correctly in  any  of  Turbo 
C's  supported  memory  models  except HUGE.  The memory model is 
defined as a macro in the MAKEFILE and is supplied  on  the  MAKE 
command line, i.e.: 

        MAKE -DM=s

to make a SMALL memory model version of CSAP  (the  "s"  must  be 
lower  case  since  it  is  a  parameter  to  TCC and TCC is case 
sensitive on its parameters).  The resultant  EXE  file  will  be 
named  CSAPx.EXE where 'x' is C,  S,  M,  or L depending upon the 
memory model selected.  There is no default memory model as  yet, 
the  desired  model  MUST  be specified on the MAKE command line.  
The current MAKEFILE will NOT work properly for the  TINY  memory 
model,  the  library specifications in the MAKEFILE would have to 
be modified to use the SMALL libraries for the TINY model and the 
effort is probably not worth it.  The command: 

        TCC -mt -G csap sortdir isdevice getdpb

would  have  to be used to produce a TINY memory model version of 
CSAP and would produce an EXE file with the name CSAP.EXE.  

The  EXE  and OBJ files in the CSAPxxx ARC have been produced for 
the COMPACT model which is probably the most general.
