Writing packages: definition of constant symbols, subroutines, types, and parameters

Description
Packages are libraries written in the Mosel language that extend the language with
  • constant symbols (myconstants.mos)
  • subroutines (definition of several overloaded versions of a procedure in solarraypkg.mos)
  • types (definition of a structure 'arc' to represent arcs in a network with a function to access information: arcpkg.mos)
  • parameters (definition of real/integer/string/boolean valued package parameters: parpkg.mos)
Further explanation of this example: 'Mosel User Guide', Chapter 16 Packages
