System Functions

System functions call the operating system to obtain information about the operating environment or to use a system service.

For many functions, the output argument can be supplied either as a field name or as a format enclosed in single quotation marks. However, if a function is called from a Dialogue Manager command, this argument must always be supplied as a format, and if a function is called from a Maintain Data procedure, this argument must always be supplied as a field name. For detailed information about calling a function and supplying arguments, see Accessing and Calling a Function.
