Global Parameters [REMOVED]
These functions are not available anymore in Metafor version greater than 2422.
Parameters are defined using prefixed codes MDE (integer) and MDR (real).

Integer parameters
All integer parameters used in Metafor are listed here. These parameters are remains of the old Fortran version of Metafor.

Real parameters
All real parameters used in Metafor are listed here. These parameters are remains of the old Fortran version of Metafor. Ideally, each option should be included in a class.
