Working with models and accessing dynamic libraries in Mosel

Description
mmexlib.java: Working with models and accessing dynamic libraries in Mosel (requires burglari.bim, chess2.bim, trans.bim)
  • load and unload BIM models
  • run a model in Mosel
  • display information about loaded models
  • display information about additional libraries required by the loaded models
mmdispmod.java: Display the contents of a model; the information is read from a bim file
  • display run-time parameters, requirements, symbols, package/module dependencies, annotations
mmdispdso.java: Display the contents of a module
  • display constants, types, control paramters, subroutines, I/O drivers
Note that these examples require the provided mos files to be pre-compiled.
