1. This parameter is used to locate packages when compiling ( XPRMcompmod) or loading a file ( XPRMloadmod). The name of the file is constructed by using each element of the list as a prefix. For instance if bimprefix has the value "tmp:||./" and it is required to load package "mypkg", the loader will try first "tmp:mypkg.bim", and then "./mypkg.bim". If none of the files created through this mechanism can be found the same procedure as for modules is used (see XPRMsetdsopath).

2. The default value for this parameter is taken from the environment variable MOSEL_BIM when Mosel is initialised.
