Format conversion functions convert fields from one format to another.
For information on field formats see the Describing Data With WebFOCUS Language or Describing Data With Graphical Tools manuals.
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 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.
