LINGO allows the input of scripts in the calc section.  These scripts are useful for running multiple models, where the outputs of one model feed into subsequent models as input.  Models are solved in calc sections with the @SOLVE command.  Time limits can be placed on @SOLVE's via the TATSLV parameter.  If a time limit is hit while @SOLVE is running, LINGO will interrupt the solve and either continue executing the script with the next command, or terminate all processing based on the setting for the KILLSC parameter (see above).  LINGO defaults to placing no time limit on @SOLVE commands.
