DTMM is a molecular modelling program, allowing molecule synthesis, editing, energy minimisation, manipulation and display on an IBM PC compatible microcomputer. The manual has an index and a useful list of mostly historical references on molecular modelling. The tutorial section starts with 'Creating alanine and investigating chirality' and ends with 'Building a peptide and using secondary display styles' which continues with an investigation of the docking facility. It is clever enough to discover I do not have a math co-processor, which is recommended, especially for those who want to use the energy minimisation features. Files saved from DTMM can optionally include information on atomic charge and type.
