Set the directory list where DSO files are stored.

By default, Mosel looks for its modules in the directories defined by the environment variable MOSEL_DSO and then in a path deduced from the location ( rtdir) of the Mosel runtime library:

"rtdir\..\dso"

Under Windows if rtdir terminates by "\bin" and "rtdir\..\dso" exists or

"rtdir/../dso"

On Unix compatible systems if rtdir terminates by "/lib" and "rtdir/../dso" exists or

"rtdir/dso"

if this directory exists or

"rtdir"

if none of the above rules apply

This function may be used to replace the directory list defined by MOSEL_DSO. Note that the directory separator is `:' under Unix (for example, "/opt/Mosel/dso:/tmp") and `;' under Win32 (for example, "E:\Mosel\Dso;C:\Temp").
