The new macro function %SYSFUNC (SASÂ® rel 6.12) allows access by the macro processor to most data step. functions and several SCL functions. Solutions to many. common macro tasks can now be simpler and more. efficient. In addition, many of the SCL functions allow the. programmer to manipulate external files directly from the.

The scientific name of each species is made up of a generic name (generic epithet) and a specific name (specific epithet). In our bluegill sunfish example the generic epithet is Lepomis and the specific epithet is macrochirus.The generic epithet is the name of the genus (singular of genera) to which bluegill sunfish belong, the genus Lepomis. Some genera contain only one species but most genera are made up of many species.There are other species of sunfish in the genus Lepomis, examples are Lepomis cyanellus (green sunfish), Lepomis megalotis (longear sunfish), and Lepomis gibbosus (pumpkinseed sunfish).n such cases one name is chosen for the species and the other names are referred to as synonyms of the species name. For example, all bats in the genus Lasiurus were once also known by the generic name Nycteris. So Lasiurus borealis would have also been known as Nycteris borealis.
