System words

System words are a set of words that provide special functionality:

• A system function runs code and may return a value; for example:
  • sysLib.minimum(arg1, arg2) returns the minimum of two numbers

  • sysLib.setLocale(language, country) does not return a value but dynamically changes the Java locale used in a Web-based application

• A system variable provides a value without invoking a function; for example:
  • sysVar.errorCode contains a status code after your program accesses a file and in other situations

  • sysVar.sqlcode contains a status code after your program accesses a relational database

For details, see System words in alphabetical order or see one of the other lists.
