ExSet.vb: Using sets in Mosel (requires burglari.mos)

• retrieve a set by its model name
• get the set size
• get first and last set element
• get the name or index of a set element

ExAs.vb: Using arrays with index sets (requires trans.mos)

• get indexing sets of an array
• get array type
• enumerate array entries in usual and transposed order
• enumerate true array entries

ExProb.vb: Accessing problems and solution information with Mosel (requires blend2.mos)

• export problem to a file (MPS or LP format)
• get problem status
• get objective function value
• get primal/dual solution values, and constraint activity

ExLib.vb: Working with models and accessing dynamic libraries in Mosel

• 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

DispMod.vb: Display the contents of a model; the information is read from a bim file

• display run-time parameters, requirements, symbols, package/module dependencies, annotations

DispDso.vb: Display the contents of a module

• display constants, types, control paramters, subroutines, I/O drivers

ExDrvs*.cb.: Use I/O drivers to handle Mosel output with a callback function, compile a model from memory to memory, load a bim file from memory, initialise arrays in the Model program from .NET objects and retrieve information from the model through memory.

• ExDrvsCallback.vb: using 'dotnet:' I/O driver for data exchange via callbacks
• ExDrvsRaw.vb: using 'dotnetraw:' I/O driver for data exchange in memory
• ExDrvsStream.vb: using 'dotnetstream:' I/O driver working with streams for data exchange in memory

These .vb files can be run from the VB.NET project Mosel-VB.NET.vbproj (required auxiliary files: frmMain.vb, frmMain.resx, OptimizerLog.vb).
