C5 Unsupported Items

Commands and Functions Not Supported by Clipper
------------------------------------------------------------------------------

 Some commands and functions of other dialects are not supported by Clipper.
 Clipper does not support any of the commands that are used primarily
 in the interactive or "dot prompt" mode.  In the interactive mode, you
 may instantly query the various databases without writing a program,
 however, Clipper has been designed to compile and execute programs
 significantly faster than can be accomplished in the interactive mode.
 The commands and functions that are not supported by Clipper
 are listed in the table below.
