In order to properly allow the user access to all phases of the simation process, one needed dynamic access to the SICUDL program for the. mchine, _ the cur!,_nt state information, the current input information, the current output information, the past history of the simulation as well as a record of any errors encountered by the simulation. built on PSL, it can be changed rapidly and customized easily be each user. In· addition, EMODE Duffers and windows can be used to interface with the surrounding PSL environment. In EMOD E, the user has the capability of setting a mode (set of legal commands) for each window, effectively making it possible to maintain a common user interface to many various tasks. EMODE (like U1ACS) takes keystrokes as commands and produces no menu of commands. There are multi-keystroke commands _ to allow for the many different procedures any given user may want to '" bind to the keyboard. The dynamiC nature of the simulation required that the user be |
