- A wetland is a distinct semi-aquatic ecosystem whose groundcovers are flooded or saturated in water, either permanently, for years or decades, or only seasonally. Flooding results in oxygen-poor (anoxic) processes taking place, especially in the soils. Wetlands form a transitional zone between waterbodies and dry lands, and are different from other terrestrial or aquatic ecosystems due to their vegetation’s roots having adapted to oxygen-poor waterlogged soils. They are considered among the most biologically diverse of all ecosystems, serving as habitats to a wide range of aquatic and semi-aquatic plants and animals, with often improved water quality due to plant removal of excess nutrients such as nitrates and phosphorus.

This manual describes the operation of the INTEL 8080 PL/M* Cross Compiler. The compiler comprises two distinct programs written in ANSI standard FORTRAN IV and may be installed on most medium to large scale computer systems. Some details presented in this manual may vary due to system dependencies and compiler options selected during the installation process. The PL/M language itself is described in the 8008 and 8080 PL/M Programming Manual.
