PATROL Script Language (PSL) Overview and functions

PSL is both an interpreted and a compiled language for writing complex application discovery procedures, parameters, and commands within the PATROL environment. It is also a good language for writing arbitrary commands and tasks. 

PSL has been designed to provide functions needed to efficiently develop KMs for the PATROL environment. To accomplish this, PSL sacrifices some of the completeness of languages such as C, csh, Perl, or awk , while implementing some of the statements and functions that make those languages so powerful and popular. Users familiar with one of those languages should have little difficulty in adapting to PSL. The following section describes some important features of PSL.
