MACCS Program Operations

Program Operations. This facility performs operations necessary to start-up, command processing, and exiting MACCS-II, as weU as allowing adjustment of some of the terminal characteristics. AdditionaUy, a command is provided to invoke external processes such as MDL s reaction indexing system, REACCS or BBN Software Products Corporation s statistics program, RS/1. 

ChemSketch is a software program developed in-house to draw chemical structures and to retrieve structures from MACCS. It is written in VAX C and will run on any of the VAX CPUs as long as they are running the VMS operating system. ChemSketch currently supports Tektronix 401x, VT-640, and VT-240 terminal emulation. 

Chemical Database Considerations. Most researchers found the menu-driven chemical database operations of MACCS friendly and with a good selection of features for their work. They also appreciated the data integration that DATACCS provided between MACCS databases and data from other programs, but the separation of the programs made some applications cumbersome, at was needed was a system that combined the capabilities of MACCS and DATACCS and that interfaced to other programs more directly. 

The General Database operation controls storage, retrieval, searching, and deletion of data in general databases that interface to MACCS-II. ORACLE or System 1032 DBMS interfaces are available from MDL. Other DBMS s that have interface architecture similar to ORACLE S may be user-programmed for use with this facility.
