Special Requirements: Fortran.                                          
                                                                        
D-ACCESS, provides access to all the functions available in the IBM DOS 
and BIOS, access to the I/O ports including the mouse and direct memory 
operations, all from FORTRAN.  No longer are you restricted to the      
functions provided by the FORTRAN compiler. Use as high level or as low 
level a function as you need.                                           
                                                                        
D-ACCESS is a set of interface modules which you can call from within   
FORTRAN with the appropriate parameters.  In most cases these parameters
are 8086/80286 register values.  The modules in turn call DOS, BIOS or  
the mouse driver, or perform direct I/O or memory operations.           
Applications where D-Access will be extremely valuable include graphics 
programs, database programs, sound programs, mouse based user interface 
programs, communication programs, and printer oriented utilities.       
                                                                        
Since effective use of DOS, BIOS, I/O, mouse or direct memory requires  
some knowledge of the 8086 family of CPUs, the IBM PC microcomputer     
family architectures, PC-DOS (or MS-DOS), BIOS and the mouse driver     
MOUSE.SYS, this program includes a recommended reading list for the     
serious programmer.
